PgBouncer does not send DISCARD ALL in transaction mode.  There is a 
separate setting to do that, but it's not the default, and it's more of 
a workaround for bad client code.  So I don't know if this feature would 
be of much use for PgBouncer.  Other connection poolers might have other 
opinions.
