Thank you for your lightning response! With such developers, sqlite is not in danger) A question along the way - is there any reason not to use flag `SQLITE_DETERMINISTIC` when declaring functions `regexp` and `regexpi`? what bad (or good or nothing) things can happen if I use it? I have found that without this flag i can't use `regexp` in the partial index (as the [docs](https://www.sqlite.org/c3ref/c_deterministic.html#sqlitedeterministic) says).
