It seems like it would often be desirable for the Oracle FDW to smash
all-upper-case names to all-lower-case while importing, so that no quoting
is needed on either side.  I doubt though that this is so desirable that
it should happen unconditionally.

Between this and the type-mapping questions, it seems likely that
we're going to need a way for IMPORT FOREIGN SCHEMA to accept
user-supplied control options, which would in general be specific
to the FDW being used.  (Another thing the SQL committee failed to
think about.)
