Support for geographic objects and geolocation queries is implemented via the PostGIS extension.

PostGIS is an open-source software extension of the PostgreSQL database management system. It enables storing, processing, and analyzing geographic data such as points, lines, and polygons. PostGIS provides various functions and operators for working with spatial data, including distance calculation, area calculation, and spatial connections.

In particular, this functionality is used by the Geodata management subsystem to store, search, and visualize data about geographic objects.
