The fact that 64-bit platforms can tackle bigger problems than 32-bit
ones is not a bug to be worked around, and so I don't see any problem
with the use of "long" for tuple counts. Furthermore, we have never
promised ABI-level compatibility across versions inside the backend,
and we are quite unlikely to make such a promise in the foreseeable
future. (Most of the time you are lucky if you get source-level
compatibility ;-).) So I can't get excited about avoiding platform
dependency in this particular tiny aspect of the API.
