Noah Misch 720e9304fa WAL-log inplace update before revealing it to other sessions. ...

A buffer lock won't stop a reader having already checked tuple
visibility.  If a vac_update_datfrozenid() and then a crash happened
during inplace update of a relfrozenxid value, datfrozenxid could
overtake relfrozenxid.  That could lead to "could not access status of
transaction" errors.

Back-patch to v14 - v17.  This is a back-patch of commits:

- 8e7e672cdaa6bfec85d4d5dd9be84159df23bb41
  (main change, on master, before v18 branched)
- 818013665259d4242ba641aad705ebe5a3e2db8e
  (defect fix, on master, before v18 branched)

It reverses commit bc6bad88572501aecaa2ac5d4bc900ac0fd457d5, my revert
of the original back-patch.

In v14, this also back-patches the assertion removal from commit
7fcf2faf9c7dd473208fd6d5565f88d7f733782b.
