You mention having a PostgreSQL database in production for around a year.
May I ask what version it is? I'm guessing you're still at 6.5.X,
in which case, I'd suggest an upgrade to 7.1.2, before doing anything
more drastic. Not only are there bug fixes, many improving stability
of the system, there are also performance enhancements, particularly in
scalability. Without knowing more details of your schema and applications
(typical queries, table sizes, etc.) we can't be of much more help.
BTW, we've had many reports of multi-gigabyte systems performing well,
and recently a report of a multi-TERA-byte system!
There have been lots of vacuum changes, as well: Bruce and Tom have made
VACUUM much friendlier to a live system since 6.5.x.
