Is this sqlite built from source or a distro sqlite? It's possible the defaults differ with build settings.

The one which avinassh shows is MacOS's SQLite under /usr/bin/sqlite3. In general it also has some other weird settings, like not having concat() method, last I checked.

The Apple built macOS SQLite is something.

Another oddity: misteriously reserving 12 bytes per page for whatever reason, making databases created with it forever incompatible with the checksum VFS.

Other: having 3 different layers of fsync to avoid actually doing any F_FULLFSYNC ever, even when you ask it for a fullfsync (read up on F_BARRIERFSYNC).

You also can't load extensions with `.load` (presumably security but a pain in the arse.)

    user ~ $ echo | /opt/homebrew/opt/sqlite3/bin/sqlite3 '.load'
    [2025-08-25T09:27:54Z INFO  sqlite_zstd::create_extension] [sqlite-zstd] initialized
    user ~ $ echo | /usr/bin/sqlite3 '.load'
    Error: unknown command or invalid arguments:  "load". Enter ".help" for help
