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.

PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: https://www.postgresql.org/download/ See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions.
