The server version where I restored the production backup is as follows - Linux *backup-server* 2.6.18-194.3.1.el5PAE #1 SMP Sun May 2 04:42:25 EDT 2010 i686 i686 i386 GNU/Linux
I read some where that, Postgres datafiles are not architecture independent.
They (the WAL files) are not, and it looks like you're trying to restore a 64-bit version onto a 32-bit server. That's not going to work. A pg_dump/restore works of course, and if you need replication then Slony can handle this.
