This involves modifying the module to have a stable ABI, that is, the
xslt_process() function still exists even without libxslt. It throws a
runtime error if called, but doesn't prevent executing the CREATE FUNCTION
call. This is a good thing anyway to simplify cross-version upgrades.
Prior to 8.3, these changes are not critical for compatibility with core
Postgres, since core had no libxml2 calls then. However there is still
a risk if contrib/xml2 is used along with libxml2 functionality in Perl
or other loadable modules. So back-patch to all versions.
Also back-patch addition of regression tests. I'm not sure how many of
the cases are interesting without the interaction with core xml code,
but a silly regression test is still better than none at all.
- add some additional files to the dbmirror install (approved by
ssinger)
- add a makefile for contrib/mysql, and add mysql to the list of
contribs build by default
- use xml2-config to pickup -I flags for libxml2 in contrib/xml and
contrib/xml2
Original work from Martin Pitt of Debian, minor cleanups by Neil
Conway.
