oid
-----------
 438094756
(1 row)

The oid that shows up in the error is 438095645.

the oid for the pl02_status_table does not show up in any of the rows in
pg_trigger that have the oid from the error in them.  The oid for the
status table does show up in a few other rows in pg_trigger (attached
file), which makes sense since its referenced in at least 2 other tables
with foreign keys, and it still is being replicated by slony so it has
that trigger on it as well.

Thanks
