PostgreSQL is designed to be highly extensible. Database extensions can be easily loaded by using CREATE EXTENSION, which automates version checks, dependencies, and other aspects of configuration.
PostgreSQL supports user-defined data types, operators, indexes, functions, and languages.
Many extensions are available for PostgreSQL, including the PostGIS extension, which provides world-class Geographical Information System (GIS) features.
