Matthew, I use this line as printed on a slackware box except the port
(5432) and the redirect at the end - on mine it is to (>) /dev/null and
here you have it reversed. Is this simply a typo in your email?
For RedHat:
What follows is Lamar Owen's script (RedHat) for firing up PG.
I simply place a call to it in rc.local so it starts on boot.
(I keep my hacked copy of Lamar's file in /usr/local/bin, the original
muzzled any logging output.) Note the rm -f of any stale locks.
Here is the line that turns on logging...
su -l postgres -c '/usr/bin/postmaster -i -D/var/lib/pgsql >> /var/lib/pgsql/postlog 2>&1 &' >/dev/null
Cheers,
Tom
