Project: QGIS

Version: 2.14.0

Feature: Use ST_RemoveRepeatedPoints for server-side simplification with PostGIS 2.2 (or newer) layers

When using a PostGIS 2.2 instance, QGIS now uses the ST_RemoveRepeatedPoints function instead of the ST_SnapToGrid function to process server-side simplification, as described by Paul Ramsey.

This method will decrease the number of vertices of the geometries that QGIS needs to download from the server, which will increase rendering speed and save bandwith between QGIS and the PostgreSQL server.
