Won't work; let's say you stop that background postgres daemon, so it is no longer doing any IO. But the upgrade then needs to stop the daemon, upgrade it's files, then start it again.

Not a problem:
1) You can stop postfix before upgrade starts.
2) You can stop postfix _inside_ the transaction. It might lead to lost data, though.
