Thanks -- v2 attached, adopting your wrapper.

One scope choice worth flagging: the wrapper suppresses only
AtEOXact_PgStat_Database() (the DB-level xact_commit/xact_rollback
counter), not all of AtEOXact_PgStat().  Per-relation and subxact stat
handling still run, so nothing accumulated during the cleanup is lost.
Renamed to AbortCurrentTransactionWithoutXactStats() to match.
