This command is just plain wrong, because the aggregation is done across
uncertain scope. Something like
update pg_class set reltriggers = (select count(*) from pg_trigger where
pg_class.oid=tgrelid)
where relname = 'foo'
would at least not run the risk of assigning wrong counts. You still
have the issue that the commands will touch every table with a given
name; there needs to be some thought about schemas here.
In general though I agree with Alvaro's comment that touching system
catalogs directly is bad practice. You should update to a PG version
that has ALTER TABLE DISABLE TRIGGER, and use that.
