- SQlite allow database to be specified as URL (given that URI filename
  interpretation was turned on on the connection.)

  This commit is necessary for the read_uncommitted transaction
  feature because SQLite doesn't allow to enable the shared-cache mode
  if the database name is `:memory:`. It has to be a URI (`file::memory`)
