Have TRUNCATE update pgstat tuple counters
This works by keeping a per-subtransaction record of the ins/upd/del
counters before the truncate, and then resetting them; this record is
useful to return to the previous state in case the truncate is rolled
back, either in a subtransaction or whole transaction. The state is
propagated upwards as subtransactions commit.
When the per-table data is sent to the stats collector, a flag indicates
to reset the live/dead counters to zero as well.
Catalog version bumped due to the change in pgstat format.
