Well for temporary disabling triggers the easiest is to run:
SET session_replication_role = replica;
UPDATE ...
SET session_replication_role = DEFAULT;
This only affects the current session i.e. you and not any other
sessions which is what you seemed to require. All this assuming you run
a supported version of postgres
