What OS and version are you running? Assuming a Debian/Ubuntu flavor for
now.

How was Postgres installed?

So there is a pid file present in the data directory, how about in the
run directory, /var/run/postgresql?

Is Postgres running? so:

ps ax|grep post

or

pg_ctl status -D /var/lib/postgresql/9.3/main

If not what happens if you remove the pid and start Postgres manually,
not through supervisor?
