Yeah, SPI users certainly shouldn't need to worry about attisdropped,
and exposing attnum doesn't seem like a good idea either.

I'm a bit reluctant to do that since it'd be nice to be consistent with
regular pltcl functions returning composites. The same kind of issue
exists with the holes in $TG_relatts; we shouldn't be exposing the
details of attnum that way. Any code that's expecting those holes is
going to blow up after a dump/restore anyway.
