Yeah, that is a better way.  In exchange for a slightly dirtier
data structure, we now have essentially all the relevant code in
makeWholeRowVar: correctness only depends on its different case
branches agreeing, rather than on some not-terribly-similar code
way over in prepjointree.c.

I also took the opportunity to split off the old-branch adjustment
of rewriteHandler.c, so that the HEAD and v15 versions of the main
bug fix patch are nearly the same.

Same data as JSON: GET /api/v1/messages/:b64id/commits the thread's linked commits as JSON, with link sources. API reference →

  1. Repair commits 317aba70e et al for -DWRITE_READ_PARSE_PLAN_TREES.

  2. Build whole-row Vars the same way during parsing and planning.

  3. Preserve RangeTblEntry.relid when expanding a view RTE.

  4. Fix incorrect non-strict join recheck in MERGE WHEN NOT MATCHED BY SOURCE.
