PostgreSQL and Solaris
PostgreSQL ships with Solaris as from the recent Solaris 10 06/06 release.
Afaik, support is provided by Sun as part of the usual Solaris support offerings.
Members of the core PostgreSQL development team have been working with Sun to make this happen.
Although this was first announced last year, when it finally did ship recently it went largely unnoticed.
Cheers,
Paul Johnson.
