An interesting obsession :)
   I have a bunch of changes in my sandbox which should make the undef 
creation
process easier. Basically, they split up the sql.in files into a
<version>_start.sql.in, common.sql.in and <version>_end.sql.in. The 
result is a
postgis.sql which should be perfectly tailored to the version. Given that, a
script modelled on the current one which just parses through the 
postgis.sql and
undefs stuff in the right order should work, though as you note some of the
semantics differ from version to version, so the create_undef.pl script will
probably get a little more complex. The more I do backwards 
compatibility the
more respect I have for microsoft (it is 2002 and we can still run DOS 
programs).
   It's interesting, at a C level, we have not had to change anything to 
support
7.3 yet, just the SQL files. We'll see though, Dave's index selectivity 
stuff
might need some upgrades.
