OK then, if there are no last-minute objects, I'll commit this for the 
upcoming minor releases.

This is the patch summary again:

Subject: [PATCH v3] Propagate ALTER TABLE ... SET STORAGE to indexes

is copied to regular (non-expression) index columns.  But a later
ALTER TABLE ... SET STORAGE is not propagated to indexes, thus
creating an inconsistent and undumpable state.
