I'm thinking instead of having struct varlena (which you're not allowed to
safely use any members of anyways) we should just have a typedef to void*.

That would make things like DATUM_GET_TEXT_PP slightly more sane as well.
text* would just be a typedef to void* which could be passed to VARDATA_ANY
and VARDATA_ANY_EXHDR but not manipulated directly.
