        Hello all, 
        On Windows, I have a 32-bit client application that uses the
          32-bit libpq.dll. In testing the client application with a
          Postgres 9.2 64-bit server I’ve noticed no problems, and was
          wondering if anyone knows of any caveats in this – AFAICS the
          tcp communication is between the 32-bit libpq and the 64-bit 
          backend is compatible. 
        

    Unless you go to considerable efforts to ensure otherwise, the
    protocol is text-based and isn't affected by endianness or word
    size. I'm not sure about the binary protocol, but it's rarely used.
