Well - I thought so, we have a logging script that logs the content of
the pg_locks table, it didn't log anything interesting but it may be a
problem with the script itself.  It does an inner join on
pg_locks.relation = pg_class.oid but when I check now this join seems
to remove most of the rows in the pg_locks table.  Does it make sense
at all to join pg_class with pg_locks?  I will ask the sysadm to
change to an outer join as for now.
