Add GUC for temporarily disabling event triggers
In order to troubleshoot misbehaving or buggy event triggers, the
documented advice is to enter single-user mode. In an attempt to
reduce the number of situations where single-user mode is required
(or even recommended) for non-extraordinary maintenance, this GUC
allows to temporarily suspend event triggers.
This was originally extracted from a larger patchset which aimed
at supporting event triggers on login events.
