we are implementing archiving/PITR for a postgresql instance operating on

If you run the same 32-bit binaries on both OpenBSD systems, it *should* work.
Anything different will not because the files will not be binary
compatible... I wonder if that is true for the minor rev number, like
9.0.0 vs. 9.0.1. That I cannot answer.
It's compatible across minor revisions like 9.0.0 and 9.0.1, but not
across major revisions like 8.4 and 9.0. You don't need the exact same
binaries, they just need to be for the same architecture (ie x86, x64,
ppc32, etc). The must have been compiled with the same set of
data-storage affecting build options, like integer timestamps.
See the FAQ for more details.
