There are lots of things in SQL that people find surprising.
In this particular case, "we can't do it because it conflicts with
ancient decisions about how PG tablespaces work" seems like a
defensible answer, even without getting into the question of
whether "partitions inherit their tablespace from the parent"
is really any less surprising than "partitions work exactly like
normal tables as far as tablespace selection goes".
