:constant SQLITE_DEFAULT_VARIABLE_LIMIT: The default number of variables that a single SQL query
can contain when interfacing with SQLite. The actual
number is set at compile time and is not easily
discoverable from within Python. This default value will
be correct for the vast majority of applications.
:constant SQLITE_DEFAULT_PRAGMAS: The default pragmas that should be used when instantiating an
SQLite database connection. The value for this constant is taken
directly from the `Peewee documentation`_
