> Implement BigQuery {{EXTRACT()}} Function. {{EXTRACT(part FROM date_expression)}} returns the value from the date_expression corresponding to the specified part. Calcite currently supports PostgreSQL' {{DATE_PART}} which has similar behavior.
> Example: {{SELECT EXTRACT(DAY FROM DATE '2013-12-25')}} would return 25.
