Well, the question is if that buys us all that much, we need the varlena
definitions to be available pretty much everywhere. Except of section 3
- which we reduced to be pretty darn small these days - of postgres.h
pretty much all of it is concerned with Datums, a good of them being
varlenas.
We could move section 1) into its own file and unconditionally include
it...
