Is there any setting that makes it possible to cache features from a PostGIS layer? (or any other layer)
- I add 20 layers from postgres
- then for every one of them set symbology
- and after this do filtering by attributes
Now if I pan across the map here and there, it starts re-reading points from Postgres db (I think). So, can QGIS cache data to memory, so it doesn't have to keep reading from the database?
