pgsql: Add ALTER TABLE ENABLE/DISABLE TRIGGER commands. - Mailing list pgsql-committers

Log Message:
-----------
Add ALTER TABLE ENABLE/DISABLE TRIGGER commands.  Change pg_dump to
use these instead of its previous hack of changing pg_class.reltriggers.
Documentation is lacking, will add that later.
Patch by Satoshi Nagayasu, review and some extra work by Tom Lane.
