I have an instance where I have a need to run 9.1-RELEASE, but my package building infrastructure is all centered around 9.3-RELEASE or later.  Based on my (possibly incorrect) understanding of How Things Are[tm], I think packages built for 9.3-RELEASE will generally run on 9.1-RELEASE.

It's possible they may work, but that is not guaranteed.

Packages built on 9.1 should work on 9.3.

Packages built on 9.3 may work on 9.1, but that would only be by chance.
