Re: transactoin id wraparound problem

Thanks

Is there a way to monitor vacuum progress. Can I resume normal
operations assuming vacuum will update the transaction ids or should I
wait till it finishes.

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.
