Sorry, wrong send earlier...
If binary packages work as expected you may just use that as a dependency, so "psycopg2-binary>=2.7.3" should do.
But now it occurs to me that the choice of not releasing a source package under psycopg2-binary was probably wrong: if you update your requirements as above, installation would fail if the user has an old pip version, or a non glibc architecture (e.g. Linux Alpine).
I'll create the missing package tomorrow morning. Once done, if your app is not a multithread program also using the system ssh, depending on binary is enough, I don't see reason for two packages.
