+## Geo Types
+Also in package exists support of PostgreSQL geo types(except Polygon for now).
+To use geo types you need specify them directly.
+
+Let's assume we have table `geo_info` with all PostgreSQL geo types in the database:
+|  database type | database column name |
+| :---: | :---: |
+| POINT | map_point |
+| BOX | point_district |
+| PATH | path_to_point |
+| LINE | points_line |
+| LSEG | lseg_between_points |
+| CIRCLE | point_radius_circle |
