in past we tried creating a plpgsql function that takes relname and schema
and try setting reltriggers=0 on disabling and = (select count(*) from pg_trigger
for that relname and schema) on enabling .
we got stuck somewhere and abandoned it , do u think above approach
would work in principle ?
i will retry it tommorw though and post the results.
