You should never edit that script, because then you'll be stuck resolving
conflicts if you upgrade and the packager makes a change to it to fix a
bug or something like that. If you want to relocate PGDATA, you should
change /etc/sysconfig/pgsql/postgresql instead and put your local
customizations there. That file is overlaid on top of the defaults just
after they're set:
# Override defaults from /etc/sysconfig/pgsql if file is present
[ -f /etc/sysconfig/pgsql/${NAME} ] && . /etc/sysconfig/pgsql/${NAME}
What I do is put *all* the defaults into that file, so that there's no
confusion about which version I'm using.
$ cat /etc/sysconfig/pgsql/postgresql
PGENGINE=/usr/bin
PGPORT=5432
PGDATA=/var/lib/pgsql/data
PGLOG=/var/lib/pgsql/pgstartup.log
The nice side-effect of this is that it makes it easy to set all these
values in a user's login profile, so that you can do things like run
pg_ctl manually instead of using the init scripts as root. Put something
like this in your profile:
. /etc/sysconfig/pgsql/postgresql
export PGDATA PGPORT PGLOG
export PATH="$PGENGINE:$PATH"
And then cycling the engine as the postgres user is as easy as:
pg_ctl start -l $PGLOG
pg_ctl stop
For my login, I add these two bits as well to make that easier, since I
never use the real start/stop commands anyway:
alias start="pg_ctl -D $PGDATA -l $PGLOG -w start && tail $PGLOG"
alias stop="pg_ctl -D $PGDATA stop -m fast"
