pgMemento provides an audit trail for your data inside a PostgreSQL database using triggers and server-side functions written in PL/pgSQL. It also tracks DDL changes to enable schema versioning and offers powerful algorithms to restore or repair past revisions.

I presented pgMemento at FOSSGIS 2015 (in german) and at FOSSGIS-NA 2016 . At FOSS4G 2017 I gave a more general overview on database versioning techniques.
Slides of the most up-to-date presentation (which are hopefully even easier to follow) can be found here. I gave the talk at the german PostgreSQL conference 2018, but the slides are in english.
A demo paper about pgMemento has been accepted at the 15th International Symposium for Spatial and Temporal Databases (SSTD) 2017 in Arlington, VA. You can find the publication here.

I would be very happy if there are other PostgreSQL developers out there who are interested in pgMemento and willing to help me to improve it. Together we might create a powerful, easy-to-use versioning approach for PostgreSQL.
