Re: transactoin id wraparound problem

Transaction ID wraparound is a cluster issue, not an individual database
issue.  Due to the way PostgreSQL is designed, you need to vacuum ALL
your databases, but you don't need a FULL vacuum on them all, just a
regular vacuum.

I'm guessing that your other databases aren't real big anyway, so it
shouldn't be a big problem.  If your other databases are huge, then
yeah, it might take a while.
