Hi,

I have tried other sources but to no avail. Could someone please tell me

which tables in pg_catalog

are effected by creating or dropping a trigger. If there is a work flow

diagram or source code location

you want to point me to rather than listing them that will be fine also.

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)

Some plonker deleted some rows directly in the pg_triggers table …. I

need to fix it.

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
