It should pretty much work.  The main thing to watch out for is that very large results sets will hit the upper limit on memory allocations.

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.

Thanks Craig and Merlin. I’ll continue with my testing of 9.2-64 bit.
