[postgis-users] how to refresh postgis layer in QGIS?

[José Pedro Santos]

Hi, 

To refresh a layer in the QGIS after making some changes in Postgis is better to remove and import the layer again. If you are using the Postgis Manager you have the option to refresh but that will only refresh the database. 

Regards,
José Santos
