Yesterday, I had twelve thousand "cache lookup failed for type N" messages, like this: 2010-09-20 00:00:00 PDT ERROR: cache lookup failed for type 14237017 2010-09-20 00:00:00 PDT CONTEXT: SQL statement "INSERT INTO mycluster.sl_log_2 (log_origin, log_xid, log_tableid, log_actionseq, log_cmdtype, log_cmddata) VALUES (1, $1, $2, nextval('mycluster.sl_action_seq'), $3, $4);" The context is always Slony sl_log_2 table. All twelve thousand errors occurred within 40 minutes. This did happen right after a Slony cluster set drop and recreate. What does "type 14237017" mean? What cache are we talking about? I am concerned because this is classified as ERROR rather than WARNING.
