Description Dave Peticolas 2001-12-26 20:03:29 EST
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.5) Gecko/20011014

Description of problem:
The postgresql /etc/init.d script detects an existing postmaster
by using pidof. This is wrong, because users can start their own
postmaster servers on user-created databases without interfering
with the main server. However, the script will not distinguish
between them and refuse to start the main server if there are
other servers running.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. /etc/init.d/postgresql stop
2.start a postmaster for a user-created database
3./etc/init.d/postgresql start



Actual Results:  The init script reports that the postmaster is already
running.

Expected Results:  It should have started a postmaster for the central
database.

Additional info:

I think it would be better to use pg_ctl's status operation
to detect a postmaster for the main database.

Seems like a good idea, will do.
Comment 2 Andrew Overholt 2003-03-12 16:56:52 EST
The initscript does not use pg_ctl yet, but multiple postmasters are now (as of
PostgreSQL version 7.3.2) supported.
