GeoTools has some custom extensions which add versioning capabilities on
top of postgis:
http://geotools.codehaus.org/Versioning+Postgis
On top of that some extensions were also built into GeoServer that
extend the WFS protocol to support versioning:
http://geoserver.org/display/GEOS/Versioning+WFS+-+Extensions
It is still experimental at this stage but people have successfully set
up working demos with it.

Hello All,
I wish to know, is there any system other than ESRI ArcSDE that supports
versioning of GeoSpatial Data.
If so could anyone point me to a possible solution in opensource and
apart from write my own custom application/Workflow from scratch.
I have tried google for solution but am not able make or break any idea
to solve this, so with a confused mind I ask, could there be
a possibility that SVN or any version control system
(application/mechanics/functionality) be merged with PostgreSQL
(Postgis) to create this solution.
Rgds.
Abhay.
