Thread: Wrong startup script of PostgreSQL 9.1.2 under OpenBSD 5.1

Wrong startup script of PostgreSQL 9.1.2 under OpenBSD 5.1

From
Denis Lapshin
Date:
On page http://www.postgresql.org/docs/9.1/interactive/server-start.html
was published a wrong startup script for automatic starting PostgeSQL
during boot under OpenBSD.

Here is a working one which should be placed into /etc/rc.local file:

if [ -x /usr/local/bin/pg_ctl -a -x /usr/local/bin/postgres ]; then
   su - _postgresql -c '/usr/local/bin/pg_ctl -D /var/postgresql/data
start -l /var/postgresql/logfile -s'
   echo -n 'postgresql'
fi

Please correct your manual pages ASAP in order to prevent spending
time to fix it.

Denis

Right offhand it's not apparent to me that either of these can be said
to be "right" or "wrong".  You are making different assumptions about
the installation directory and user name than what is in the
documentation, but your assumptions aren't more right than the docs'.
As stated there, the examples use generic choices that may need to be
adjusted for particular systems.

Hello there,

I have already posted this problem several months ago, there was no change
in the documentation since then. It's not about the installation directory
or username, under the new OpenBSD's the parameter ordering of 'su' differs
from the older versions, the right order is like Denis writes.

Ah, okay (and I confirmed this with a bit of googling).  Will fix,
thanks for the explanation.

BTW, a little further googling turns up the information that this isn't
OpenBSD-specific; there are a number of platforms where "su -c" doesn't
act like it does on Linux.  But "su username -c 'command'" works the
same everywhere.  I'll adjust the generic text as well as the OpenBSD
paragraph in light of this.
