-- The SQLiteZSTD library is initialized first with `sqlitezstd.Init()`.
 - The `sql.Open()` function takes as a parameter the path to the compressed
   SQLite database, appended with a query string with `vfs=zstd` to use the VFS.
 - Setting the `PRAGMA` ensures that the read only VFS is not used to create
