How to install PMM tool to monitor PostgreSQL?

Hi, Planning to install and evaluate the features available in percona to monitor PostgreSQL.
My environment is Ubuntu 4.8 and PostgreSQL 9.3.14. Please gudie me how to install server and client.
Also let me know how to create the dash board.

Verified below links, but unable to find the solution.

Before you go any further be advised that PMM supports only those versions of postgres that are currently supported by the community. Version 9.3 reached end of life on November 8th 2018

Your version of Ubuntu, if it is Ubuntu 4.10 (Warty Warthog) also reached end of life in 2006.
You might want to confirm and if this is the case you’ll need to upgrade both your OS and version of postgres
