MediaWiki's Website now mentions PostgreSQL support more prominently on their requirements page than in the past:
http://www.mediawiki.org/wiki/Manual:Installation_guide Previously, they had advocated MySQL as being the preferred back-end, but the necessary PostgreSQL scripts was mentioned deep down in their documentation. The Makefile for OpenBSD's MediaWiki port: http://www.openbsd.org/cgi-bin/cvsweb/ports/www/mediawiki/Makefile?rev=1.37 ...mentions php-pgsql as being the necessary connector to PostgreSQL, but I'm not finding it in the ports tree. Where is it? Thanks.
