I am looking for a robust connection pooling library for Postgresql.
Something similar to https://github.com/dweldon/riakpool would be great.
Poolboy is a pretty good general-purpose pooling library: https://github.com/devinus/poolboy
It comes with an example of how to use it with pgsql (scroll down the README file).
