Be pickier about converting between Name and Datum.
We were misapplying NameGetDatum() to plain C strings in some places.
This worked, because it was just a pointer cast anyway, but it's a type
cheat in some sense. Use CStringGetDatum instead, and modify the
NameGetDatum macro so it won't compile if applied to something that's
not a pointer to NameData. This should result in no changes to
generated code, but it is logically cleaner.
Mark Dilger, tweaked a bit by me
