Great, big errors ... Again.

Ok, it appears the database backend is being stupid again, I'm getting all
kinds of errors.

From my PHP code, I'm getting this kind of error now:

heap_beginscan:
!RelationIsValid(relation) in classes/db_pgsql.inc on line 63
Database error: Invalid SQL: select
user_id_hash,session_id,user_id,agency_id,date_part('epoch',created) as
start,date_part('epoch',updated) as age from users_online where
user_id_hash='9de5085eac89de8be0169b6dc6801524'
PostgreSQL Error: 1 (ERROR: heap_beginscan: !RelationIsValid(relation) )
Session halted

I got "Sorry, too many clients already" -- a little while ago..

I'm running at debug level 3, but have nothing to show for it in the log
file except this :

NOTICE: Message from PostgreSQL backend:
The Postmaster has informed me that some other backend died
abnormally and possibly corrupted shared memory.
I have rolled back the current transaction and am going to terminate
your database system connection and exit.
Please reconnect to the database system and repeat your query.
/usr/local/pgsql/bin/postmaster: CleanupProc: sending SIGUSR1 to process
44639
/usr/local/pgsql/bin/postmaster: CleanupProc: reinitializing shared memory
and semaphores
shmem_exit(0) [#0]

So.. Now that I've got it to break, any ideas on what I can do to figure out
why it's happening? This is still a 6.5.3 server.. (I weas going to upgrade
today believe it or not.)
