There were plans to add such functionality for ages, but nothing ever got into the codebase... Issue #3200 has an old patch attached, mainly for an inspiration. I would love to have this functionality in QGIS - not only for PostGIS, but more generic framework for caching of vector features. I believe this will bring another boost to the rendering performance, not only for remote connections, but also for local data sources that are non-trivial to parse or that do not support spatial index or attribute index natively. It would be great to have a common framework in QGIS that would do: 1. feature storage 2. spatial indexing (R-tree) 3. attribute indexing (B-tree) 4. full-text indexing All that based on pages, with maximum allowed memory usage, with ability to swap pages to disk etc. SQLite looks like a good backend for such thing.
