Michael Paquier b1e48bbe64 Include replication origins in SQL functions for commit timestamp ... This includes two changes: - Addition of a new function pg_xact_commit_timestamp_origin() able, for a given transaction ID, to return the commit timestamp and replication origin of this transaction. An equivalent function existed in pglogical. - Addition of the replication origin to pg_last_committed_xact(). The commit timestamp manager includes already APIs able to return the replication origin of a transaction on top of its commit timestamp, but the code paths for replication origins were never stressed as those functions have never looked for a replication origin, and the SQL functions available have never included this information since their introduction in 73c986a. While on it, refactor a test of modules/commit_ts/ to use tstzrange() to check that a transaction timestamp is within the wanted range, making the test a bit easier to read. Bump catalog version.
