Note that this is also a kind of bogus assumption. PostgreSQL is not
generally substantially faster than SQLite, it just has better support for
concurrent writing and it has auto vacuuming (which can improve
performance, but irrelevant if you vacuum manually).

I don't think the switch alone is motivation on its own for writing heavier
weight queries... What I would like to see is infrastructure for doing
those queries in the background and caching results better.
