Dear Leo and Regina (and everyone else too):
Thanks very much for your detailed reply. I'm just now to the point
where I've implemented your recommendations, but no positive outcome
yet. I simplified the addresses to address the regex expression variable
error, performed a soft upgrade to 2.0.1, and cleaned up my query (both
with and without the use of pgScript).
New PostGIS version:
"POSTGIS="2.0.1 r9979" GEOS="3.3.5-CAPI-1.7.5" PROJ="Rel. 4.8.0, 6 March
2012" GDAL="GDAL 1.9.1, released 2012/05/15" LIBXML="2.7.8" ...etc.
New Query:
SELECT a.rid, a.respondent, a.s_year, Coalesce((g.geo).rating,-1)
"rating", (g.geo).geomout "the_geom"
FROM respondents_addr a
LEFT JOIN
(
SELECT respondent, s_year, (geocode(address, 1)) "geo"
FROM respondents_addr
ORDER BY rid LIMIT 100
) g
ON a.respondent = g.respondent
AND a.s_year = g.s_year
WHERE a.address IS NOT NULL
ORDER BY rid LIMIT 100;
Same Error Message:
ERROR: invalid regular expression: quantifier operand invalid
CONTEXT: PL/pgSQL function "normalize_address" line 386 at assignment
PL/pgSQL function "geocode" line 10 at assignment
And yet the following query still returns good results in 43320 ms:
SELECT (normalize_address(address)).* FROM respondents_addr WHERE
address IS NOT NULL LIMIT 1000;
Wait. As I typed the last bit I realized the normalization test query is
not ordered the same way as the geocode query.
This fails with the exact same error:
SELECT (normalize_address(address)).* FROM respondents_addr WHERE
address IS NOT NULL ORDER BY rid LIMIT 100;
I'm not very familiar with regular expressions. Is anyone willing to
look at these first 100 addresses, sent off-list, and tell me which are
tripping me up and why?
Thanks,
Rob

Rob,
Regarding your normalize issue, it's probably one record causing it. I
thought we fixed some of these issues in 2.0.1 and 2.1.0SVN so you might
want to upgrade your script to the 2.0.1 -- there is an upgrade script
you can use packaged in the tar ball.
If that still doesn't fix your issue, look for variables often found in
regex expressions in your address (things like (, ) and . for example
might be throwing it off and we might not be escaping right. Hard to
tell which one until your narrow down to the one bad record.
You might have to run each update as a single to see which one fails
Couple of other tips
1) you don't want to geocode 100K records all at once since it has to
complete as a single transaction. You'll need to do it in batches. We
use pgScript for that batch processing so we can just run in a pgAdmin
window. though any scripting tool of your choice would do.
http://www.postgresonline.com/journal/archives/181-pgAdmin-pgScript.html
2) Don't do (geocode(address)).* That often calls geocode for each
field in output so would slow down your processing n fold (e.g. you'd
have like 5 calls instead of 1)
You really want to do geocode(address) As geo
(geo).geomout etc.
See example in docs --
http://www.postgis.org/documentation/manual-svn/Geocode.html -- we do a
left join to guarantee that even if no records returned for an address,
we can stamp the address as attempted with a -1 rating
I think we thought about this after we wrote the book :(
-- SHAMELESS PLUG STARTS HERE ---
On bright side, we just signed our contract for Second Edition of
PostGIS in Action and have started writing it :) more on that later.
that will cover newer enhancements in geocoder, raster, topology,
PostGIS 2.0-2.1 (basically at least 2.0 and 2.1 changes) and PostgreSQL
9.1-9.3
We'll be posting the new Table Of Contents soon here, and let people
know when they can start purchasing
http://www.postgis.us
Those who buy the new book, is our understanding, will automatically get
electronic copies of the first edition, so even if you buy early, you'll
get our drafts as we write them and also have the older book to work
with.
-- END SHAMELESS PLUG
3) The book was written before we introduced the limit, so again look
at:
http://www.postgis.org/documentation/manual-svn/Geocode.html (feature
is available in 2.0 as well)
Use: geocode(address,1)
for faster performance and then you don't even need the DISTINCT ON
since you'll get back at most one answer and the best one.
Hope that helps,
Leo and Regina

Subject: [postgis-users] Geocode function fails when
callingnormalize_address
Hi All:
My batch geocode of 100K records is failing with error messages that
refer to an operand in the normalize_address function. I based my
single-column UPDATE on the multi-column example in "PostGIS In Action"
and have tweaked the syntax only to achieve slight variation in the
error message.
The query is something like:
UPDATE respondents_addr SET the_geom =
g.geomout
FROM (SELECT DISTINCT ON (respondent, s_year) respondent, s_year,
(geocode(address)).*
FROM respondents_addr As ra
WHERE ra.address IS NOT NULL
ORDER BY respondent, s_year, rating) As g
WHERE g.respondent = respondents_addr.respondent
AND g.s_year = respondents_addr.s_year;
The most frequent error text is:
ERROR: invalid regular expression: quantifier operand invalid
CONTEXT: PL/pgSQL function "normalize_address" line 386 at assignment
PL/pgSQL function "geocode" line 10 at assignment
********** Error **********
ERROR: invalid regular expression: quantifier operand invalid
SQL state: 2201B
Context: PL/pgSQL function "normalize_address" line 386 at assignment
PL/pgSQL function "geocode" line 10 at assignment
Also the query runs for more than an hour, (xp box with 3.5 GB ram,
PosgreSQL 9.0.6, PostGIS 2.0.0 (might be the problem?)) and no matter
how the error message changes it always references the normalization
function, so I tried:
SELECT (normalize_address(address)).* FROM respondents_addr WHERE
address IS NOT NULL LIMIT 1000;
With the LIMIT it ran quickly and returned the expected result, so I
tried:
SELECT (normalize_address(address)).* FROM respondents_addr WHERE
address IS NOT NULL LIMIT 5000;
Bumping the LIMIT up reproduced the error from the geocode attempts. I'd
say "aha" if only I knew why.
I checked the list archives and googled several combinations of words
from the error but alas, to no avail. I suspect that I've either
repeated a simple syntax error or that my setup is somehow off -- any
help will be appreciatedand I might as well close with results of
PostGIS_full_version():
POSTGIS="2.0.0 r9605" GEOS="3.3.3-CAPI-1.7.4" PROJ="Rel. 4.8.0, 6 March
2012" GDAL="GDAL 1.9.0, released 2011/12/29" LIBXML="2.7.8"

based my single-column UPDATE on the multi-column example in "PostGIS In Action"
and have tweaked the syntax only to achieve slight variation in the error
message.</FONT></P>
<P><FONT face=Arial size=2>The query is something like:</FONT> </P><BR>
<P><FONT face=Arial size=2>UPDATE respondents_addr SET the_geom =</FONT>
<BR><FONT face=Arial size=2> g.geomout</FONT> <BR><FONT face=Arial
size=2> FROM (SELECT DISTINCT ON (respondent, s_year) respondent,
s_year, (geocode(address)).*</FONT> <BR><FONT face=Arial
size=2> FROM respondents_addr As ra</FONT>
<BR><FONT face=Arial size=2>
WHERE ra.address IS NOT NULL</FONT> <BR><FONT face=Arial
size=2> ORDER BY respondent, s_year, rating) As
g</FONT> <BR><FONT face=Arial size=2> WHERE
g.respondent = respondents_addr.respondent</FONT> <BR><FONT face=Arial
size=2> AND g.s_year =
respondents_addr.s_year;</FONT> </P><BR>
<P><FONT face=Arial size=2>The most frequent error text is:</FONT> </P><BR>
<P><FONT face=Arial size=2>ERROR: invalid regular expression: quantifier
operand invalid</FONT> <BR><FONT face=Arial size=2>CONTEXT: PL/pgSQL
function "normalize_address" line 386 at assignment</FONT> <BR><FONT face=Arial

face=Arial size=2>********** Error **********</FONT> <BR><FONT face=Arial

<P><FONT face=Arial size=2>Also the query runs for more than an hour, (xp box
with 3.5 GB ram, PosgreSQL 9.0.6, PostGIS 2.0.0 (might be the problem?)) and no
matter how the error message changes it always references the normalization
function, so I tried:</FONT></P><BR>
<P><FONT face=Arial size=2>SELECT (normalize_address(address)).* FROM
respondents_addr WHERE address IS NOT NULL LIMIT 1000;</FONT> </P><BR>
<P><FONT face=Arial size=2>With the LIMIT it ran quickly and returned the
expected result, so I tried:</FONT> </P><BR>
<P><FONT face=Arial size=2>SELECT (normalize_address(address)).* FROM
respondents_addr WHERE address IS NOT NULL LIMIT 5000;</FONT> </P><BR>
<P><FONT face=Arial size=2>Bumping the LIMIT up reproduced the error from the
geocode attempts. I'd say "aha" if only I knew why.</FONT> <BR><FONT face=Arial
size=2>I checked the list archives and googled several combinations of words
from the error but alas, to no avail. I suspect that I've either repeated a
simple syntax error or that my setup is somehow off -- any help will be
appreciatedand I might as well close with results of
PostGIS_full_version():</FONT></P><BR>
