I'm wondering if this (and also my deadlocks stats patch that's int he
queue) should instead of inventing new pgstats messages, add fields to
the tabstat message. It sounds like that one is just for tables, but
it's already the one collecting info about commits and rollbacks, and
it's already sent on every commit.
Adding two fields to that one would add some extra bytes on every
send, but I wonder if that woudl ever affect performance, given the
total size of the packet? And it would certainly be lower overhead in
the cases that there *have* been temp tables used.
