There are a number of industry-standard laptops on the ISS, so whether they're running Linux, Windows or macOS, SQLite is in them. But I don't know if it's being used for space/research purposes. There was some publicity that Norton Anti-Virus (which uses SQLite) has been run on a computer on the shuttle. I stumbled across a NASA search engine while looking for something else and tried 'sqlite' in it: <https://ntrs.nasa.gov/search?q=sqlite> Numerous hits, of course. Nothing mentioning Perseverance, but some suggestion that SQLite is in use off earth in storing experimental results. And SQLite is definitely used on earth for various NASA testing systems. So SQLite is definitely in orbit, but perhaps not on any other planet.
