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.
