You can sometimes do "apt-get install postgresql-9.3=9.3.4-1"

But often the OS cannot work out where to get hold of the requested version.

Alternatively you can check in /var/cache/apt/archives.
If the .deb file for the downlevel version is still there (copy it out so
it's not cleaned up in future), and you can do "dpkg -i postgres-9.3_9.3.4-1
.deb"

Failing that, you can download the downlevel deb file from somewhere.
(perhaps here? https://launchpad.net/ubuntu/+source/postgresql-9.3 )
