Vote on SET in aborted transaction

OK, would people please vote on how to handle SET in an aborted
transaction?  This vote will allow us to resolve the issue and move
forward if needed.

In the case of:

	SET x=1;
	BEGIN;
	SET x=2;
	query_that_aborts_transaction;
	SET x=3;
	COMMIT;

at the end, should 'x' equal:
	
	1 - All SETs are rolled back in aborted transaction
	2 - SETs are ignored after transaction abort
	3 - All SETs are honored in aborted transaction
	? - Have SETs vary in behavior depending on variable

Our current behavior is 2.

Please vote and I will tally the results.
