Обсуждение: Is it possible to convert WAL's between architectures?
As in the title - is it possible to convert WAL for another architecture? (source database on Linux/i386, contemplating chances to restore backup on Linux/amd64)

We did this by installing the 32 bit libraries and making a 32 bit build which ran under the 64 bit OS. -Kevin

True. But that would only work on 64/32 split OSes where the chipsets have a 32 bit compatibility mode. You couldn't do that from i386 to sparc64 for instance.
