 #### Summary
 
+- PostGIS plugin: added `key_field_as_attribute` option. Defaults to `True` to preserve current behavior of having the `key_field` added both
+  as an attribute and as the `feature.id` value. If `key_field_as_attribute=false` is passed then the attribute is discarded (https://github.com/mapnik/mapnik/issues/3115)
 - CSV plugin has been further optimized and has gained experimental support for on-disk indexes (https://github.com/mapnik/mapnik/issues/3089)
 - SVG parser now fallsback to using `viewbox` if explicit dimensions are lacking (https://github.com/mapnik/mapnik/issues/3081)
 - Visual tests: new command line arguments `--agg`, `--cairo`, `--svg`, `--grid` for selecting renderers (https://github.com/mapnik/mapnik/pull/3074)
