Hearing nothing, committed after fixing few things:
- The docs reversed <parameter> and <type>.
- The comment on top of GetLatestCommitTsData() mentioned "extra"
instead of "nodeid". Not an issue of this patch but I have just fixed
it.
- We could just have used memset for nulls when the data could not be
found in pg_xact_commit_timestamp_origin().
- Added some casts to Oid for the new ObjectIdGetDatum() calls.
- Changed the tests to not show numerical values for roident, checking
instead that the values are non-zero for the cases where we don't
expect a valid replication origin. For the valid cases, I have just
used a join with pg_replication_origin to grab roname. This makes the
tests more portable.

After applying the patch as of b1e48bb, longfin has also complained
that regression tests should prefix replication origins with
"regress_". This has been fixed with ea3e15d.
