Still, running the vacuum in the background is not a good idea, because some
people tend to issue the next port command right after the previous one exited
(I sure do) and would probably end of mystified why the database was still locked
(and VACUUM requires an exclusive lock) while the previous port process has
already exited.

I'd argue for reducing the frequency at which VACUUM is run (for example until
a certain threshold of free pages is reached) and adding output indicating that
MacPorts is doing some cleanup work.
