The maximum number of parameters supported by the FE/BE protocol is 65535, as it's transmitted as a 16-bit unsigned integer. However, the nParams arguments to libpq functions are all of type 'int'. We can't change the signature of libpq functions, but a simple bounds check is in order to make it more clear what's going wrong if you try to pass more than 65535 parameters. Per complaint from Jim Vanns.
