Please read from bottom up. I've proceeded further with this
investigation and have removed slony. In spite of this the trigger in
pg_trigger and pg_dep remained. I then removed both related records in
pg_depend and pg_trigger.
If I look in pg_class, it shows that there are 4 triggers on the table
which previously owened the trigger. I no longer have any reference to
this oid in pg_depend or pg_trigger.
Yet, after restarting postgres and all client connections, I now get the
ERROR: 1 trigger record(s) not found for relation
As mentioned, I've checked the for relating oid's in pg_depend and
If anyone else has manually done something similar before, I would be
grateful for some guidence.
