Log message:
	Repair memory leakage introduced into the non-hashed aggregate case by
	7.4 rewrite for hashed aggregate support.  If the transition data type
	is pass-by-reference, the transValue must be pfreed when starting a new
	group boundary, else we have a one-value-per-group leakage.  Thanks to
	Rae Steining for providing a reproducible test case.
