Can QGIS cache a PostGIS layer for faster rendering?

Is there any setting that makes it possible to cache features from a PostGIS layer? (or any other layer)

For example:

• 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?
