server closed the connection unexpectedly

Hi,

I get this error when accessing the postgresl database  -- any ideas? What should I look at?

I can query all of the other tables in the database, just not the email_queue table. Weird!

Thanks in advance,
Mark

# psql --version
psql (PostgreSQL) 7.3.2

# psql

count
-------

(1 row)

mncis2-rel=# select count(*) from email_queue;
server closed the connection unexpectedly
        This probably means the server terminated abnormally
        before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.
