You should look at PostgreSQL Automatic Failover project:
http://dalibo.github.io/PAF/
It relies on the Pacemaker project, the industry reference for HA under Linux.
Make sure to consult the documentation, especially the quick starts:
http://dalibo.github.io/PAF/documentation.html
Installation: http://dalibo.github.io/PAF/install.html
Here is some conference slides including video of demos:

PAF only requiers streaming replication between nodes. Whether you want it sync
or async is your choice.
2.0 is perfect for production. 2.1 with minor improvements should be out before
2017 hopefully (see github commit history if curious).
It appears PAF 2.0 (or 2.1 if released before 2017) might be included in
Debian 9. There is a pending discussion with a Debian packager.
