If it were, we'd throw it overboard for sure.
The one thing we _never_ restart is the postmaster. We see no
degradation in performance from this.
My suspicion is that, if you find restarting the postmaster helps, it
might be because of a long-running transaction which is hanging
around and keeping VACUUM from doing its job. Killing the postmaster
will certainly get rid of such transactions, but there are probably
less dire ways to do it ;-)
