> If the query plan in SQLite looks good, it'll stay good. In a real database, you're sitting on a timebomb waiting to go off when autoanalyze ends up running at a bad time.
That's unfortunately naive. For example, for a certain type of query there are two possible plans. Which one is better depends on the parameters to the plan and the distribution of the data, and getting the plan wrong can be the difference between the query finishing and the query not finishing. With a stability guarantee you can't even try to make an intelligent choice based on the parameters.
