An exclusive lock will block selects too. Have you looked into pg_locks

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.
You can also enable log_lock_waits and the lock waits will appear in
your Postgres logs.
