The format of the rpmdb does not only depend on the rpm version but also
on the bdb version rpm is built against. In general you should not need
to care about the rpmdb compatibility when packaging software as rpm

Typically packages build with newer versions of RPM should also work
with older rpm-4.x versions. There are a couple of new features that
need to be turned off like SHA1 checksums and xz compression or must not
be used like ~ in version or release.

The release notes of the 4.x.0 versions should give you a good hint on
what to avoid in their compatibility sections. See .
