AFAIK you can't mix the two in the same executable image. If you are stuck using a 32-bit-only library, you'll have to build all of the Postgres server as 32-bit. Note that this is probably not going to cost all that much performance-wise, so I wouldn't recommend expending any great amount of sweat to avoid it. regards, tom lane
