Обсуждение: Disable Constraints in Postgresql 8.4

I want to execute a sql file for that I need to disable constraints.
In postgres version 8.3,  I was executing the script by doing the
following:
1.    Disabling triggers by updating “reltriggers” field of pg_class to 0 .
2.    Executing sql file
3.    Then updating “reltriggers” field of pg_class by “select count(*) from
pg_trigger where pg_trigger.tgrelid=pg_class.oid”

In postgres version 8.4, “pg_class” table does not have “reltriggers” field.

How can I disable and enable constraints in Postgres Version 8.4?

See ALTER TABLE DISABLE TRIGGER.  (Fooling with reltriggers has been
deprecated since 8.1.)
