Обсуждение: Portability of pgsql database files.

I have a system that is dual bootable for both i686 and x86_64.  Would
there be any issues using the PostgreSQL database files generated for
i686 on x86_64, or vice versa?

Thanks!

Uh, if the padding is the same, it would work, but we never test such
things.

You'd probably have problems with the different data alignment rules for
the two architectures (I'm supposing MAXALIGN is different, though
perhaps it is not?).
