What that looks like is that the package's upgrade script forgot to stop
the old postmaster version before trying to start the new one; or perhaps
slightly more likely, failed to wait for the old postmaster to finish
stopping.
Either way, that would be a bug in the packaging, which you should take
up with the Debian package maintainer, not with the upstream project.
