Good day.

often, I am turning triggers off and on to perform a mass operation on a
table, and i am interested how should i care of another user operations.

the scene is:
table t1 with user defined triggers
and many tables reference t1, (so FK triggers defined on t1)

the operation i want to perform on t1 makes a great load to a server
and have no use in triggers at all.
the best way to perform this operation is to delete all records, modify, and
insert them back without changing any adjuscent table.
(this way takes a few seconds.)
so i turn off triggers on t1 completely (updating pg_class.reltriggers)
operate
and turn on triggers on t1.

it works fine.

the question is:

what should i do to prevent other users of data modification on the t1 and the
adjuscent tables while triggers is off ?

thnx.


P.S.
...what about TEXT to REGCLASS casting ?
