Thank you first.
I believe that upate pg_class can only be done by superuser, right?
Besides, if I need the whole schema's foreign keys to be disabled and
then enabled later.
Is there a simple command could do it? Similar to mysql's "set
FOREIGN_KEY_CHECKS = false/true"?

Good morning,
Is there a way to temporally disabled foreign key constraints
something like:
SET FOREIGN_KEY_CHECKS=0
When population is done, will set FOREIGN_KEY_CHECKS=1
You can disable *triggers* on a table (which will disable all the FK
constraints, but not things like 'not nul' or 'unique').
For Disable:
update pg_class set reltriggers=0 where relname = 'TEST';
For Enable:
update pg_class set reltriggers = count(*) from pg_trigger where
pg_class.oid=tgrelid and relname='TEST';
