Although I agree it is not worth a lot of trouble, and even if I don't do
Windows, I think it valuable that the behavior is the same on all
platform. The attached match shares pg_str2*int64 functions between
frontend and backend by moving them to "common/", which avoids some code
duplication.
This is more refactoring, and it fixes the behavior change on 32 bit
architectures.
