A message from your friendly MediaWiki maintainer: If you use MediaWiki on OpenBSD with the PostgreSQL database, be careful when updating PostgreSQL from 8.2.x to 8.3.x, a dump and restore is not enough:
Dump your wiki database. Split the dump into to files, the first one containing only database and Wiki user creation. The second the rest. Run the first part against the server using psql. enter psql and connect to your Wiki database. Read in tsearch2 using \i /usr/local/share/postgresql/contrib/tsearch2.sql Now run the second part against the server. Without doing it approx. this way, your MediaWiki will go offline... - Marc
