Replace ALTER TABLE ... SET STATISTICS DISTINCT with a more general mechanism.

Browse Source 
Attributes can now have options, just as relations and tablespaces do, and
the reloptions code is used to parse, validate, and store them.  For
simplicity and because these options are not performance critical, we store
them in a separate cache rather than the main relcache.

Thanks to Alex Hunsaker for the review.
