Re: problem with RETURNING and update row movement

I noticed that this bugfix has stalled, probably because the other
bugfix has also stalled.

It seems that cleanly returning system columns from table AM is not
going to be a simple task -- whatever fix we get for that is likely not
going to make it all the way to PG 12.  So I suggest that we should fix
this bug in 11-13 without depending on that.
