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...
