Modified files:
openpkg-src/postgresql postgresql.patch postgresql.spec
Log:
A small patch to allow DSO-based PostgreSQL extensions to be more
flexible by providing initialization and finishing hooks. This patch was
contributed by Ralf S. Engelschall to the upstream vendor in August 2006
and taken over by the upstream vendor for inclusion into the next major
PostgreSQL release.

PS: This allows my OSSP uuid's PostgreSQL extension to finally do the Right
Thing ;-)
