Re: a misbehavior of partition row movement (?)

Pushed 0001.

I had to adjust the query used in pg_dump; you changed the attribute
name in the query used for pg15, but left unchanged the one for older
branches, so pg_dump failed for all branches other than 15. Also,
psql's describe.c required a small tweak to a version number test.

Thanks! What was 0002 is attached, to keep cfbot happy. It's identical
to your v11-0002.

I have pushed it thinking that we would not backpatch any of this fix.
However, after running the tests and realizing that I didn't need an
initdb for either patch, I wonder if maybe the whole series *is*
backpatchable.

There is one possible problem, which is that psql and pg_dump would need
testing to verify that they work decently (i.e. no crash, no
misbehavior) with partitioned tables created with the original code.
But there are few ABI changes, maybe we can cope and get all branches
fixes instead of just 15.

What do you think?
