Seems like this exposes a generic weakness in the way pgstat.c is coded.
I'm inclined to adjust the switch logic in PgstatCollectorMain along
the lines of
- pgstat_recv_inquiry((PgStat_MsgInquiry *) &msg, len);
+ pgstat_recv_inquiry(&msg.msg_inquiry, len);
so that you *couldn't* forget to extend the union, as long as you
followed the existing code's style.
