This looks pretty useful to me. I just threw it into the current
CommitFest, on the basis that there's already so many other thing trying
to whack around pg_stat_statements right now we might as well keep them
together. Let me clear my queue of patches submitted on time I need to
do something with (re-review Scott Mead's pg_stat_activity change,
respond to Jeff Janes on relation free space) and I'll take a quick spin
on this one.
