It sounds like the service-start case is picking a different data
directory than you're expecting --- likely /var/lib/postgres, or
whatever the installation default is.

I'm not sure what's in Mandrake 10, but I can tell you that in the Red
Hat RPMs, putting a PGDATA definition into ~/.bash_profile did not work
until very very recently.  The init script did
    su - postgres -s /bin/sh -c "postmaster ..."
thus forcing /bin/sh to be used, and /bin/sh won't pay any attention
to ~/.bash_profile.

This is fixed in recent RPMs (basically by removing "-s /bin/sh"), or
you can dodge the problem by copying the variable definitions into
regular sh's ~/.profile.
