Yeah, that's what you get if you let pg_restore try to determine the
file type.  If you tell it you know that the file is an archive (-Fc)
then it believes you, and you get the lower-level failure.

I'm not real sure why we honor -Fc and -Ft in pg_restore anyway;
skipping the file type check couldn't possibly save enough to be
worth the trouble ...
