Thread: pgsql: Remove ancient kluge that kept nodeAgg.c from crashing on UPDATEs

Log Message:
-----------
Remove ancient kluge that kept nodeAgg.c from crashing on UPDATEs involving
aggregates.  We just disallowed that, and AFAICS there should be no other
cases where direct (non-aggregated) references to input columns are allowed
in a query with aggregation and no GROUP BY.

        nodeAgg.c (r1.139 -> r1.140)
        (http://developer.postgresql.org/cvsweb.cgi/pgsql/src/backend/executor/nodeAgg.c.diff?r1=1.139&r2=1.140)
