That seems just about impossible from a concurrency standpoint
(ie, what if someone is creating a new table in the tablespace
concurrently with your check?  Possibly in a different database?)

I would certainly suggest that the first version of the patch not
undertake to allow this property to be ALTERed; the cost-benefit
ratio isn't there IMO.
