# Applied Patches
Michaël Paquier pushed:
- Improve some error wording with multirange type parsing. Braces were referred
in some error messages as only brackets (not curly brackets or curly braces),
which can be confusing as other types of brackets could be used. While on it,
add one test to check after the case of junk characters detected after a right
brace. Author: Kyotaro Horiguchi Discussion:

https://git.postgresql.org/pg/commitdiff/12cc956664f159e97be71e33f15ec5f42e46b24e)
- Ignore more environment variables in TAP tests. Various environment variables
were not getting reset in the TAP tests, which would cause failures depending
on the tests or the environment variables involved. For example,
PGSSL{MAX,MIN}PROTOCOLVERSION could cause failures in the SSL tests. Even
worse, a junk value of PGCLIENTENCODING makes a server startup fail. The list
of variables reset is adjusted in each stable branch depending on what is
supported. While on it, simplify a bit the code per a suggestion from Andrew
Dunstan, using a list of variables instead of doing single deletions.

- Reduce risks of conflicts in internal queries of REFRESH MATVIEW CONCURRENTLY.
The internal SQL queries used by REFRESH MATERIALIZED VIEW CONCURRENTLY
include some aliases for its diff and temporary relations with rather-generic
names: diff, newdata, newdata2 and mv. Depending on the queries used for the
materialized view, using CONCURRENTLY could lead to some internal failures if
the matview query and those internal aliases conflict. Those names have been
chosen in 841c29c8. This commit switches instead to a naming pattern which is
less likely going to cause conflicts, based on an idea from Thomas Munro, by
appending `_$` to those aliases. This is not perfect as those new names could
still conflict, but at least it has the advantage to keep the code readable
and simple while reducing the likelihood of conflicts to be close to zero.

Tom Lane pushed:
- Fix mis-planning of repeated application of a projection.
create_projection_plan contains a hidden assumption (here made explicit by an
Assert) that a projection-capable Path will yield a projection-capable Plan.
Unfortunately, that assumption is violated only a few lines away, by
create_projection_plan itself. This means that two stacked ProjectionPaths
can yield an outcome where we try to jam the upper path's tlist into a
non-projection-capable child node, resulting in an invalid plan. There isn't
any good reason to have stacked ProjectionPaths; indeed the whole concept is
faulty, since the set of Vars/Aggs/etc needed by the upper one wouldn't
necessarily be available in the output of the lower one, nor could the lower
one create such values if they weren't available from its input. Hence, we
can fix this by adjusting create_projection_path to strip any top-level
ProjectionPath from the subpath it's given. (This amounts to saying "oh, we
changed our minds about what we need to project here".) The test case added
here only fails in v13 and HEAD; before that, we don't attempt to shove the
Sort into the parallel part of the plan, for reasons that aren't entirely
clear to me. However, all the directly-related code looks generally the same
as far back as v11, where the hazard was introduced (by d7c19e62a). So I've
got no faith that the same type of bug doesn't exist in v11 and v12, given the
right test case. Hence, back-patch the code changes, but not the irrelevant
test case, into those branches. Per report from Bas Poot. Discussion:

- Reject SELECT ... GROUP BY GROUPING SETS (()) FOR UPDATE. This case should be
disallowed, just as FOR UPDATE with a plain GROUP BY is disallowed; FOR UPDATE
only makes sense when each row of the query result can be identified with a
single table row. However, we missed teaching CheckSelectLocking() to check
groupingSets as well as groupClause, so that it would allow degenerate
grouping sets. That resulted in a bad plan and a null-pointer dereference in
the executor. Looking around for other instances of the same bug, the only
one I found was in examine_simple_variable(). That'd just lead to silly
estimates, but it should be fixed too. Per private report from Yaoguang Chen.
Back-patch to all supported branches.

- Fix planner's row-mark code for inheritance from a foreign table. Commit
428b260f8 broke planning of cases where row marks are needed (SELECT FOR
UPDATE, etc) and one of the query's tables is a foreign table that has regular
table(s) as inheritance children. We got the reverse case right, but
apparently were thinking that foreign tables couldn't be inheritance parents.
Not so; so we need to be able to add a CTID junk column while adding a new
child, not only a wholerow junk column. Back-patch to v12 where the faulty
code came in. Amit Langote Discussion:

- Re-allow custom GUC names that have more than two components. Commit 3db826bd5
disallowed this case, but it turns out that some people are depending on it.

should fall in line. Per bug #17045 from Robert Sosinski. Discussion:

- Fix incorrect permissions on pg_subscription. The documented intent is for all
columns except subconninfo to be publicly readable. However, this has been
overlooked twice. subsynccommit has never been readable since it was
introduced, nor has the oid column (which is important for joining). Given
the lack of previous complaints, it's not clear that it's worth doing anything
about this in the back branches. But there's still time to fix it
inexpensively for v14. Per report from Israel Barth (via Euler Taveira).

- Fix postgres_fdw failure with whole-row Vars of type RECORD. Commit 86dc90056
expects that FDWs can cope with whole-row Vars for their tables, even if the
Vars are marked with vartype RECORDOID. Previously, whole-row Vars generated
by the planner had vartype equal to the relevant table's rowtype OID. (The
point behind this change is to enable sharing of resjunk columns across
inheritance child tables.) It turns out that postgres_fdw fails to cope with
this, though through bad fortune none of its test cases exposed that. Things
mostly work, but when we try to read back a value of such a Var, the expected
rowtype is not available to record_in(). Fortunately, it's not difficult to
hack up the tupdesc that controls this process to substitute the foreign
table's rowtype for RECORDOID. Thus we can solve the runtime problem while
still sharing the resjunk column with other tables. Per report from Alexander
Pyhalov. Discussion:

Peter Eisentraut pushed:
- Fix RADIUS error reporting in hba file parsing. The RADIUS-related checks in
parse_hba_line() did not respect elevel and did not fill in `*err_msg`. Also,
verify_option_list_length() pasted together error messages in an
untranslatable way. To fix the latter, remove the function and do the error
checking inline. It's a bit more verbose but only minimally longer, and it
makes fixing the first two issues straightforward. Reviewed-by: Magnus

- Remove unnecessary use of Time::HiRes from 013_crash_restart.pl. The
regression test 013_crash_restart.pl included "use Time::HiRes qw(usleep)",
but the usleep was not used there. Author: Fujii Masao Reviewed-by: Kyotaro

- Revert most of 39b66a91bd. Reverts most of commit 39b66a91bd, which was found
to cause significant regression for REFRESH MATERIALIZED VIEW. This means only
rows inserted by heap_multi_insert will benefit from the optimization,
implemented in commit 7db0cd2145. Reported-by: Masahiko Sawada Discussion:

David Rowley pushed:
- Standardize usages of appendStringInfo and appendPQExpBuffer. Fix a few places
that were using appendStringInfo() when they should have been using
appendStringInfoString(). Also some cases of appendPQExpBuffer() that would
have been better suited to use appendPQExpBufferChar(), and finally, some
places that used appendPQExpBuffer() when appendPQExpBufferStr() would have
suited better. There are no bugs are being fixed here. The aim is just to
make the code use the most optimal function for the job. All the code being
changed here is new to PG14. It makes sense to fix these before we branch for
PG15. There are a few other places that we could fix, but those cases are
older code so fixing those seems less worthwhile as it may cause unnecessary
back-patching pain in the future. Author: Hou Zhijie Discussion:

- Clean up some questionable usages of `DatumGet*` macros. This tidies up some
questionable coding which made use of DatumGetPointer() for Datums being
passed into functions where the parameter is expected to be a cstring. We saw
no compiler warnings with the old code as the Pointer type used in
DatumGetPointer() happens to be a `char *` rather than a `void *`. However,
that's no excuse and we should be using the correct macro for the job. Here
we also make use of OutputFunctionCall() rather than using FunctionCall1()
directly to call the type's output function. OutputFunctionCall() is the
standard way to do this. It casts the returned value to a cstring for us. In
passing get rid of a duplicate call to strlen(). Most compilers will likely
optimize away the 2nd call, but there may be some that won't. In any case,
this just aligns the code to some other nearby code that already does this.

Andrew Dunstan pushed:
- In PostgresNode.pm, don't pass SQL to psql on the command line. The Msys shell
mangles certain patterns in its command line, so avoid handing arbitrary SQL
to psql on the command line and instead use IPC::Run's redirection facility
for stdin. This pattern is already mostly whats used, but query_poll_until()
was not doing the right thing. Problem discovered on the buildfarm when a new
TAP test failed on msys.

environment variables were not getting reset in the TAP tests, which would cause \
failures depending on the tests or the environment variables involved. For example,
PGSSL{MAX,MIN}PROTOCOLVERSION could cause failures in the SSL tests. Even
worse, a junk value of PGCLIENTENCODING makes a server startup fail. The list
of variables reset is adjusted in each stable branch depending on what is
supported. While on it, simplify a bit the code per a suggestion from Andrew
Dunstan, using a list of variables instead of doing single deletions.

CONCURRENTLY. The internal SQL queries used by REFRESH MATERIALIZED VIEW \
CONCURRENTLY include some aliases for its diff and temporary relations with \
rather-generic names: diff, newdata, newdata2 and mv. Depending on the queries used \
for the materialized view, using CONCURRENTLY could lead to some internal failures \
if the matview query and those internal aliases conflict. Those names have been
chosen in 841c29c8. This commit switches instead to a naming pattern which is
less likely going to cause conflicts, based on an idea from Thomas Munro, by
appending <code>_$</code> to those aliases. This is not perfect as those new names \
could still conflict, but at least it has the advantage to keep the code readable
and simple while reducing the likelihood of conflicts to be close to zero.

mis-planning of repeated application of a projection. create_projection_plan \
contains a hidden assumption (here made explicit by an Assert) that a \
projection-capable Path will yield a projection-capable Plan. Unfortunately, that \
assumption is violated only a few lines away, by create_projection_plan itself. \
This means that two stacked ProjectionPaths can yield an outcome where we try to jam \
the upper path's tlist into a non-projection-capable child node, resulting in an \
invalid plan. There isn't any good reason to have stacked ProjectionPaths; indeed \
the whole concept is faulty, since the set of Vars/Aggs/etc needed by the upper one \
wouldn't necessarily be available in the output of the lower one, nor could the \
lower one create such values if they weren't available from its input. Hence, we
can fix this by adjusting create_projection_path to strip any top-level
ProjectionPath from the subpath it's given. (This amounts to saying "oh, we
changed our minds about what we need to project here".) The test case added
here only fails in v13 and HEAD; before that, we don't attempt to shove the
Sort into the parallel part of the plan, for reasons that aren't entirely
clear to me. However, all the directly-related code looks generally the same
as far back as v11, where the hazard was introduced (by d7c19e62a). So I've
got no faith that the same type of bug doesn't exist in v11 and v12, given the
right test case. Hence, back-patch the code changes, but not the irrelevant
test case, into those branches. Per report from Bas Poot. Discussion:

Commit 86dc90056 expects that FDWs can cope with whole-row Vars for their tables, \
even if the Vars are marked with vartype RECORDOID. Previously, whole-row Vars \
generated by the planner had vartype equal to the relevant table's rowtype OID. \
(The point behind this change is to enable sharing of resjunk columns across
inheritance child tables.) It turns out that postgres_fdw fails to cope with
this, though through bad fortune none of its test cases exposed that. Things
mostly work, but when we try to read back a value of such a Var, the expected
rowtype is not available to record_in(). Fortunately, it's not difficult to
hack up the tupdesc that controls this process to substitute the foreign
table's rowtype for RECORDOID. Thus we can solve the runtime problem while
still sharing the resjunk column with other tables. Per report from Alexander
Pyhalov. Discussion:

There are no bugs are being fixed here. The aim is just to make the code use the \

It makes sense to fix these before we branch for PG15. There are a few other places \

macros. This tidies up some questionable coding which made use of DatumGetPointer() \
for Datums being passed into functions where the parameter is expected to be a \
cstring. We saw no compiler warnings with the old code as the Pointer type used in
DatumGetPointer() happens to be a <code>char *</code> rather than a <code>void \
*</code>. However, that's no excuse and we should be using the correct macro for \
the job. Here we also make use of OutputFunctionCall() rather than using \
FunctionCall1() directly to call the type's output function. OutputFunctionCall() is \
the standard way to do this. It casts the returned value to a cstring for us. In
passing get rid of a duplicate call to strlen(). Most compilers will likely
optimize away the 2nd call, but there may be some that won't. In any case,
this just aligns the code to some other nearby code that already does this.
