I make a patch as Michael Paquier described that use a new function to
return transactionid and origin, and I add a origin version to
pg_last_committed_xact() too, now it looks like below:
============================================
postgres=# SELECT txid_current() as txid \gset
postgres=# SELECT * FROM pg_xact_commit_timestamp_origin(:'txid');
timestamp | origin
-------------------------------------+--------
2020-07-04 17:52:10.199623+08 | 1
(1 row)
postgres=# SELECT * FROM pg_last_committed_xact_with_origin();
xid | timestamp | origin
-----+------------------------------------+--------
506 | 2020-07-04 17:52:10.199623+08 | 1
(1 row)
postgres=#
============================================
