pgFoundry
The official home of many PostgreSQL-related projects is pgFoundry: http://pgfoundry.org/.
pgFoundry only hosts software for PostgreSQL, and it provides resources like mailing lists and bug tracking in addition to file distribution. Many of the most popular PostgreSQL add-on programs are hosted there:
- Windows software allowing access to PostgreSQL through .Net and OLE
- Connection poolers like pgpool and pgBouncer
- Database management utilities like pgFouine, SkyTools, and pgtune
While sometimes maintained by the same people who work on the PostgreSQL core, pgFoundry code varies significantly in quality. One way to help spot the healthier projects is to note how regularly and recently new versions have been released.
