[postgis-users] Data Versioning?

[Craig Miller]

SDE is ESRIs Spatial Database Engine.  It supports versioning for GeoSpatial
data the same way that CVS does this for code.  CVS will not work for this
purpose, as Spatial Data stored in PostGIS is not stored in flat text files
like source code.  Postgres / PostGIS would need to support this directly.

I don't have the answer to the question, but am also very interested to know
if Postgres/PostGIS support any form of geospatial data versioning.  I am
also curious to know if it supports long transactions.  I should probably
RTFM before asking though.
