It sounds like we are running low on volunteers and developers who actually run PostgreSQL day-to-day. So here are some fairly easy places to reach out to Postgres users and developers:
- PgDay, Sunday, July 24, 2011, in Portland just before OSCON
- San Francisco's PostgreSQL Meetup Group, Tuesday, July 12, 2011, 7:00 PM
- Maybe submit a talk requesting MediaWiki support at PgWest? PostgreSQL conference, September 27th - 30th, San Jose.
- People who have talked about MediaWiki on Postgres mailing lists
I'm happy to find the mailing list folks but MW developers are far better placed to make contact in user groups or give talks.
