I'm using the OS X precompiled binary from EnterpriseDB and want to add the tablefunc contrib module. I haven't been able to find any documentation about how to do this or even whether modules can be added to this binary version.
I suppose that it may be a good idea to export my databases and compile from source anyway. I see that Postgres is running as a 32-bit application while I have a 64-bit machine and OS (OS X, Snow Leopard.)
