Oh understood. Tomas suggested those commands too earlier. I'll implement them. But I think it is better to track files modification time too. Because now, without the patch, users don't have to call additional commands to refresh their dictionaries, so without such tracking we'll made dictionaries maintenance harder.
Postgres hasn't any subsystem based on modification time, so introduction this sensitivity, I don't see, practical.
