Hello all, I have been working on a versioning system to be used with QGIS.
This is probably a very naive approach since I'm no expert in Postgres, but I would like to ear some comments and suggestions to improve it. The work is based on the versioning system of QGIS, but I wanted to improve two things: 1 - Keep always the same primary key of features; 2 - Only save\backup changed columns instead of the full similar rows; Thanks for your help Alexandre Neto
