Really, what *ought* to happen in such a case is that the FDW gets
told about the command and has the opportunity to try to do something
corresponding to making an index. But that smells like a new feature
rather than a bug fix.

I'm not sure that just forcing the case to be a no-op is wise.
What if the index is supposed to be UNIQUE?
