I'm still in favor of pg_xact. A search of the 9.6 docs brings up a
number of hits for "xact": pg_last_xact_replay_timestamp(),
pg_advisory_xact_lock(), pg_advisory_xact_lock_shared(),
pg_last_committed_xact(), pg_prepared_xacts(), etc. There are also
numerous column names that have "xact" in them.

It's not just an arcane developer term when it shows up in a number of
our user-facing functions/columns.
