These functions should return SETOF TEXT[], like the core functions they
are wrappers for; but they were incorrectly declared as returning just
TEXT[]. This mistake had two results: first, if there was no match you got
a scalar null result, whereas what you should get is an empty set (zero
rows). Second, the 'g' flag was effectively ignored, since you would get
only one result array even if there were multiple matches, as reported by
Jeff Certain.
While ignoring 'g' is a clear bug, the behavior for no matches might well
have been thought to be the intended behavior by people who hadn't compared
it carefully to the core regexp_matches() functions. So we should tread
carefully about introducing this change in the back branches. Still, it
clearly is a bug and so providing some fix is desirable.
After discussion, the conclusion was to introduce the change in a 1.1
version of the citext extension (as we would need to do anyway); 1.0 still
contains the incorrect behavior. 1.1 is the default and only available
version in HEAD, but it is optional in the back branches, where 1.0 remains
the default version. People wishing to adopt the fix in back branches will
need to explicitly do ALTER EXTENSION citext UPDATE TO '1.1'. (I also
provided a downgrade script in the back branches, so people could go back
to 1.0 if necessary.)
This should be called out as an incompatible change in the 9.5 release
notes, although we'll also document it in the next set of back-branch
release notes. The notes should mention that any views or rules that use
citext's regexp_matches() functions will need to be dropped before
upgrading to 1.1, and then recreated again afterwards.
Back-patch to 9.1. The bug goes all the way back to citext's introduction
in 8.4, but pre-9.1 there is no extension mechanism with which to manage
the change. Given the lack of previous complaints it seems unnecessary to
change this behavior in 9.0, anyway.
Prominent binaries already had this metadata. A handful of minor
binaries, such as pg_regress.exe, still lack it; efforts to eliminate
such exceptions are welcome.

This isn't fully tested as yet, in particular I'm not sure that the
"foo--unpackaged--1.0.sql" scripts are OK. But it's time to get some
buildfarm cycles on it.
sepgsql is not converted to an extension, mainly because it seems to
require a very nonstandard installation process.

match the convention that foo's uninstall script is uninstall_foo.sql.
Also, stop installing lo_test.sql, which really ought to be made into
a regression test anyway (though it's unclear how to avoid a dependency
on the current OID counter...)

written a generic framework of rules that the contrib makefiles can
use instead of writing their own each time. You only need to set a few
variables and off you go.
Cygwin with the possible exception of mSQL-interface. Since I don't
have mSQL installed, I skipped this tool.
Except for dealing with a missing getopt.h (oid2name) and HUGE (seg),
the bulk of the patch uses the standard PostgreSQL approach to deal with
Windows DLL issues.
I tested the build aspect of this patch under Cygwin and Linux without
any ill affects. Note that I did not actually attempt to test the code
for functionality.
The procedure to apply the patch is as follows:
$ # save the attachment as /tmp/contrib.patch
$ # change directory to the top of the PostgreSQL source tree
$ patch -p0 </tmp/contrib.patch

source directory. This involves mostly makefiles using $(srcdir) when they
might have used ".". (Regression tests don't work with this, yet.)
Sort out usage of CPPFLAGS, CFLAGS (and CXXFLAGS). Add "override" keyword
in most places, to preserve necessary flags even when the user overrode the
flags.
* Add option to build with OpenSSL out of the box. Fix thusly exposed
bit rot. Although it compiles now, getting this to do something
useful is left as an exercise.
* Fix Kerberos options to defer checking for required libraries until
all the other libraries are checked for.
* Change default odbcinst.ini and krb5.srvtab path to PREFIX/etc.
* Install work around for Autoconf's install-sh relative path anomaly.
Get rid of old INSTL_*_OPTS variables, now that we don't need them
anymore.
* Use `gunzip -c' instead of g?zcat. Reportedly broke on AIX.
* Look for only one of readline.h or readline/readline.h, not both.
* Make check for PS_STRINGS cacheable. Don't test for the header files
separately.
* Disable fcntl(F_SETLK) test on Linux.
* Substitute the standard GCC warnings set into CFLAGS in configure,
don't add it on in Makefile.global.
* Sweep through contrib tree to teach makefiles standard semantics.
... and in completely unrelated news:
* Make postmaster.opts arbitrary options-aware. I still think we need to
save the environment as well.

This patch fix the Makefiles in contrib/{pginterface, spi,
miscutil, int8, ip_and_mac, sequence, soundex, string, userlock,
array, datetime} to install their modules in one directory(lib/modules/).
