i don’t want to be such a partisan for analyze, but the query planner deciding not to use an index based on information collected by analyze is not necessarily a bug, but could be the correct choice.

<s>the original poster in that stack overflow doesn’t say there’s a performance regression </s>

Found one report on Stack Overflow from 9 years ago of someone seeing broken performance after running ANALYZE, hard to say that's a trend and not a single weird edge-case though! https://stackoverflow.com/q/12947214/6083

The reason I'm hesitating on this is that I've not actually used ANALYZE at all in nearly five years of messing around with SQLite! So I'm nervous that there are surprise downsides I haven't thought of.

My hunch is that ANALYZE is only worth worrying about on much larger databases, in which case I'm OK supporting it as a thoroughly documented power-user feature rather than a default.
