We're hoping PostgreSQL can match or beat Sybase performance, and preliminary tests look good. We should be able to get some load testing going within a week, and we're shooting for slipping these machines into the mix around the end of this month. (We've gone to some lengths to keep our code portable.)
Just make sure to set up and run the contrib/pg_autovacuum daemon, or make sure you fully read 'regular database maintenance' in the manual.
