Tom Lane b4a0223d00 Simplify and improve ProcessStandbyHSFeedbackMessage logic. ...

There's no need to clamp the standby's xmin to be greater than
GetOldestXmin's result; if there were any such need this logic would be
hopelessly inadequate anyway, because it fails to account for
within-database versus cluster-wide values of GetOldestXmin.  So get rid of
that, and just rely on sanity-checking that the xmin is not wrapped around
relative to the nextXid counter.  Also, don't reset the walsender's xmin if
the current feedback xmin is indeed out of range; that just creates more
problems than we already had.  Lastly, don't bother to take the
ProcArrayLock; there's no need to do that to set xmin.

Also improve the comments about this in GetOldestXmin itself.
