Thanks for rebasing - I actually started to do that yesterday.
I extracted the bits from your original 0001 patch which handled CLUSTER and
VACUUM FULL. I don't think if there's any interest in combining that with
ALTER anymore. On another thread (1), I tried to implement that, and Tom
pointed out problem with the implementation, but also didn't like the idea.
I'm including some proposed fixes, but didn't yet update the docs, errors or
tests for that. (I'm including your v8 untouched in hopes of not messing up
the cfbot). My fixes avoid an issue if you try to REINDEX onto pg_default, I
think due to moving system toast indexes.
template1=# REINDEX DATABASE template1 TABLESPACE pg_default;
