postgresql-dump .. catch 22 ?

Hmm .. I seem to have reached a catch-22.

I had 7.2 installed, apt-upgraded to 7.8.4
I tried to apt-remove and then apt-install postgres, which may have just
removed parts of 7.2
When I try to run 'postgresql-dump', it fails telling me it cannot start
the postmaster.

But when I try to start the postmaster

>> Tux:~# /etc/init.d/postgresql restart
>> Stopping PostgreSQL database server: postmasterpg_ctl: could not find
>> /var/lib/p ostgres/data/postmaster.pid

.. it tells me to run postgresql-dump.

I confess to being a postgres newbie, but there has to be a way around.
