I don't know if its completely right, but when a trigger is created the following catalog are affecteds:
- pg_trigger (new entry)
- pg_depend (new entry)
- pg_class (update relhastriggers column)

Maybe you simply DROP and CREATE trigger solve it...

Fabrizio,

Thank you very much for your email, I was able to run a script to generate update statements to the tables you mentioned and this has fixed my problem for me.

select 'UPDATE pg_catalog.pg_class SET reltriggers=' || b.reltriggers-1 || ' WHERE relname=' || '''' || a.table_name || '''' || ' and oid=' || b.oid

from information_schema.tables a, pg_catalog.pg_class b

where a.table_type = 'BASE TABLE'

and a.table_schema = 'public'

and a.table_name not like '%dbmirror%'

and a.table_name = b.relname

order by a.table_name asc

Many Thanks

Graham
