PGDATA in 9.3.5-1 upgrade on Centos 5.4

Hi,

I have a quick question about upgrading postgresql-server rpm from 9.3.4-1PGDG.rhel5 to 9.3.5-1PGDG.rhel5 on Centos 5.4.

As highlighted below, the 9.3.5 rpm seems to overwrite PGDATA variable at ~postgres/.bash_profile. We have our database at a different location and this breaks a lot of scripts and admins.
Is PGDATA from now on fixed at /var/lib/pgsql/version/data or is this maybe a bug slipped into this particular rpm? If the rpm is fine, how should we run the DB in a non-default directory?

cheers,
