Turning on logging of the Mapnik SQL query during map rendering #987

Closed kolisko closed 1 month ago

kolisko commented 1 year ago

I have connected Mapnik to PostGIS and I am using a datasource. I would like to view the SQL query that is executed when the render() method is called. I have attempted this without success. Any idea?

 (mapnik as any).logger.set_severity((mapnik as any).severity_type.Debug);
 (mapnik as any).Logger.setSeverity((mapnik as any).Logger.DEBUG);

In my experience the most useful and easy thing to do is to turn on logging at the database level.
