I don't buy Simon's argument that we should treat TABLESPACE
differently because the tables might be really big and take a long
time to move. I agree that this could well be true, but nobody is
proposing to remove the ability to move tables individually or to use
ONLY here. Allowing TABLESPACE to recurse just gives people one
additional choice that they don't have today: to move everything at
once. We don't lose any functionality by enabling that.
Doing that would add the single largest footgun in Postgres, given that command's current behavior and the size of partitioned tables.
If it moved partitions concurrently I'd feel differently.
