That isn't a supported configuration. The standby needs to be the same 
architecture as the master and needs to use the same compilation options.

I'm surprised the error message wasn't more useful in this case.

It still won't work. If you want to replicate from a 64-bit machine to a 
32-bit machine you will need to build a 32-bit version of PostgreSQL on 
the 64-bit machine.
