Re: BUG #19367: typos in backend/utils/adt/timestamp.c

There are typos in return type of these functions:
1) timestamptz_pl_interval_at_zone(PG_FUNCTION_ARGS)
    NOW: PG_RETURN_TIMESTAMP(timestamptz_pl_interval_internal(timestamp,
span, attimezone));
    SHOULD:
PG_RETURN_TIMESTAMPTZ(timestamptz_pl_interval_internal(timestamp, span,
attimezone));
2) Datum timestamptz_mi_interval_at_zone(PG_FUNCTION_ARGS)
    NOW: PG_RETURN_TIMESTAMP(timestamptz_mi_interval_internal(timestamp,
span, attimezone));
    SHOULD:
PG_RETURN_TIMESTAMPTZ(timestamptz_mi_interval_internal(timestamp, span,
attimezone));
