Hi! Attached is a patch for my request. Added the possibility to add the parameter PGXLOG to an environment file in /etc/sysconfig/pgsql/ and have it picked up bythe initdb function. I also removed some strange indention for the LOCALE parameter section in that function. I tested this with the following environment in /etc/sysconfig/pgsql/pgtest01 PGENGINE=/usr/pgsql-9.3/bin PGPORT=5440 PGDATA=/var/lib/pgsql/data/9.3/pgtest01 PGLOG=/var/lib/pgsql/log/pgtest01/pgstartup.log PGXLOG=/var/lib/pgsql/xlog/9.3/pgtest01 Created the link in /etc/init.d # ln -s postgresql-9.3 pgtest01 Created the needed directories and set the correct owner: # mkdir -p /var/lib/pgsql/data/9.3/pgtest01 # mkdir -p /var/lib/pgsql/log/pgtest01 # mkdir -p /var/lib/pgsql/xlog/9.3/pgtest01 # chown postgres:postgres /var/lib/pgsql/data/9.3/pgtest01 # chown postgres:postgres /var/lib/pgsql/xlog/9.3/pgtest01 # chown postgres:postgres /var/lib/pgsql/log/pgtest01 Use the follwing commands to initdb and start the postgres server: # service pgtest01 initdb # service pgtest01 start To start on boot add # chkconfig pgtest01 on Please review and let me know what you think.

Hmm your email ended up in my Junk mail folder, so sorry for my late response. Yes, that would've been good, but no rush. Anyway, I also did see that LOCALE could be specified as input to the initdb function. Perhaps it would be reasonable to add that as well as an option in the /etc/sysconfig/pgsql files? I will look into a patch, hopefully in the coming week or so.

I wish you sent this mail 2 days before, while we were working on updated releases, so that we could add this feature to today's updates. I created http://wiki.pgrpms.org/ticket/145 for this, and added you as a CC, so that you can see the progress. I think we can add this feature in next update set.
