Hi,

we can't simply put .so files for an arbitrary PostgreSQL version into
a postgresql-debversion.deb because that will break existing
installations on dist upgrade.

What we can do is to "Provides: postgresql-debversion" from each of
the postgresql-X.Y-debversion packages. That should fix your
deployment problem. (However, it won't make upgrades work, because
it doesn't keep the PostgreSQL and extension versions in sync.)

Does that help for your case?
