Disable trigger with Postgresql 7.4.x?

Hello,

I read in an old thread

http://archives.postgresql.org/pgsql-hackers/2002-08/msg00079.php

... that starting with Postgresql 7.3, there is a new way to disable and
enable triggers in Postgresql. The "old" way was:

update pg_class set reltriggers=0 where relname = 'YOUR_TABLE_NAME';
update pg_class set reltriggers = count(*) from pg_trigger where
pg_class.oid=tgrelid and relname='YOUR_TABLE_NAME';

What is the recommended way of doing that under Postgresql 7.4.x?

Thanks

Philippe Lang
