Add-ons are slim. Slony. We don't have any C based functions and only a
few plpgsql functions in that DB.
I did trim out a ton of autovacuum log entries (it likes to log once a
minute) but I don't see anything interesting in that area nor autovac
the pid that exited.
My knowledge of signal handling is pretty basic. Any chance that
multiple SIGTERMs could have caused it to avoid the logging?
