commit    b58bacdacbb15948cf24c786ebbb92213a2fe013
Author:   Joe Conway <mail@joeconway.com>
Date:     Thu May 10 05:57:19 2012 +0000
First released in: 9.2.0, 8.4.12, 9.0.8, 9.1.4

    PL/pgSQL RETURN NEXT was leaking converted tuples, causing
    out of memory when looping through large numbers of rows.
    Flag the converted tuples to be freed. Complaint and patch
    by Joe.
