Berkeley DB uses a completely different SONAME versioning system that
doesn't have a version number after the *.so part.  You should not follow
its example.  That versioning strategy, while possible, is much less usual
and is intended for packages where the SONAME is closely tied to the
release version of the package.

You can maintain multiple versions of a shared library in Debian with
either SONAME versioning system.  The key requirement of coinstallability
of multiple versions of the library is that the library MUST use symbol
versioning properly so that the libraries can coexist in memory without
tromping on each other.
