[Qgis-user] Changing data source from Postgis to Geopackage

[Alessandro Pasotti]

If you mean change data source functionality, this is now available in
https://github.com/qgis/QGIS/pull/8359

There is also a new "Change data source..." menu entry in the layer's
contextual menu, implemented for rasters and vectors.
