pg_dump help

I am trying to copy a table from my local database to a client's. The
problem is I keep getting a message from pg_dump:

"can't find template1 database. You are really hosed."

The docs say that this usually means the postmaster is not running but it
is. In fact, I can get into the database and do whatever I want to with it.
Over the weekend I did try and install the 7.0.2 RPMS without much luck. I
uninstalled them and reinstalled 6.5.1-3. I then reloaded my databases.
This is the first time I've done a pg_dump since. pg_dumpall gives me the
same error.

If you've got any advice on how I can save these two tables I need so I can
get them to my customer I'd appreciate it.

Redhat 6.0 OS
