From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.1a) Gecko/20020610 Description of problem: The way postgresql is currently packaged it is hard to change the location of the database (i.e. PGDATA) without modifying the startup script (which will get overwritten on updating). A better way of setting PGDATA (rather than fixing it to /var/lib/pgsql) would be to see what the home directory of the postgres user is set to and use that.
If you have a nice, clean patch which doesn't lead to problems for initscripts, file ownership etc, you can attact it. Other than that, I don't see a need and the current way works well - and handles issues like recognizing older versions of the database and issueing approriate warnings.
