This isn't very clear. Are you saying that you successfully updated to
9.1 and now you have a pg_dump performance problem you didn't have before?
Or are you still on 9.0 and you are just now finding out that you can't
pg_dump (that is, you don't have any routine backup policy)?
Also, 9.0.what and 9.1.what? We've fixed a number of pg_dump
performance issues with huge schemas in the last year or two, but it's
impossible to guess whether you have those fixes.
