Are you dumping the whole database or just a single table? If it's
the former, try the latter and see if you still get errors.
If pg_dump is not working, maybe some system table is hosed. What
errors are you getting?
If you can get in via psql, log in as a superuser and execute:
COPY mytable TO 'mytable.txt';
That will dump the table data to a text file which can be re-imported
into a new database using the COPY FROM command. Basically you're
just doing part of what pg_dump does for you by hand.
