Hm, well, file_fdw already goes through COPY FROM, so it seems like it'd
almost just work. "Almost" because there'd need to be a way for it to
support the appropriate options. So this means that whatever the
mechanism is for extension-specific options, it has to be introspectable
enough for file_fdw.c to understand what to expose as FDW options.
