As Markus suggests, it's highly unlikely that Postgres is failing
without any message whatsoever. What is more likely is that the message
is being sent somewhere you're not looking, or there is a permissions
problem or something with where it was told to send it. Take a look at
the init script you're using to start the server, and see where it sends
the postmaster's stderr. You need to check that in case of failures
that occur before the configured log destination has taken effect.
(I have seen some scripts that redirect stderr to /dev/null :-( ...
if you have one of those, change it, and file a bug report with the
packager.)
