Обсуждение: A question about postmaster and postgresql commands

Hi!
Can anybody tell me what the difference between postmaster and posgresql is?
More accurately, what's the difference between running the following
commands?

/usr/local/pgsql/bin/postmaster -D /usr/local/pgsql/data >logfile 2>&1 &

and

/etc/init.d/postgresql start


Thanks a lot in advance!

Agustin

It starts the postmaster-process. This is the main process of pg.

This is a unix-like start/stop - script. You have any other scripts like
this, and you can run this scripts like '/etc/init.d/SCRIPT start' or
with 'stop' as parameter tu start/stop several services in the same way.


Please do a 'less /etc/init.d/postgresql', and you can see how this
script works.
