betterthan special disable_client_connection_trigger GUC.

session_start.This event should be started after connecting - so the exception there doesn't block connect, and should
bestarted also after the new statement "DISCARD SESSION", that will be started automatically after DISCARD ALL. This
featureshould not be implemented in first step, but it can be a plan for support pooled connections

I've created a separate patch to address question (1), rather than
include it in the main patch, which I've adjusted accordingly. I'll
leave question (2) until another time, as you suggest.
See the attached patches.
