It seems that to get rid of the error, I only need to close my connections
to the databases with the problem, rather than shutdown the postmaster.

I'm unable to find a set of steps that reproduce it. It seems to happen
after the jboss server has been running (and has had a connection to the
database) for a couple of days.

I'm running vacuumdb from cron every morning at 3 AM. How often should I
run vacuumdb? What exactly does it do?
In the above link, Tom Lane said
"The first backend to fire up after a vacuum will try to rebuild
pg_internal.init, and then move it into place."
Perhaps I should restart my jboss server every time I run vacuumdb, so the
files will be released.
