Versioning Postgis datastore allows to version enabled one or more feature types stored in Postgis, extract features at a specific revision, log changes, rollback them, and extract differences.


Geoserver is leading this effort in order to pursue the versioning WFS, a building block in the larger GeoCollaboration vision.

Target Audience

By being part of the GeoTools library, this datastore allows anyone to enjoy version control at the spatial data level.
In particular, this is compelling for the following use cases:

Quality Assurance

The module has high level of unit testing code coverage, 81.2% at the time of writing.
The datastore is supposed to handle both versioning and non versioning use cases, and has been designed to make versioning transparent to users, so the unit tests perform:


The module is in good health. No self or transient issues preventing it from compiling and passing tests.
