I wrote this while sitting in Andrew Sullivan's session on PostgreSQL project management. During Q&A, people discussed how to manage various feature proposals.
I should probably note here that a couple of weeks before the PGCon, we heard about a major US research institution looking into 64 bit
PostgreSQL on Solaris for a large astronomy project.
(Note: Sun Microsystems already sells PostgreSQL support for Solaris. You can also learn more about OpenSolaris and databases for OpenSolaris, here.)
