PostGIS is a spatial database extension which adds support for geographic objects.
PostGIS has been under development since ca. 2001 and is one of the few third-party extensions mentioned in the PostgreSQL documentation.
Release history
"Point releases" (e.g. 2.5.0) are (since 2015) released approximately once a year, to coincide with the release of a new major PostgreSQL version. Support for the oldest PostgreSQL version supported by the previous release will then be dropped.
This list notes the date of the main "point releases" and the PostgreSQL versions they are compatible with; for a detailed list of changes, click on the "NEWS" link which references the relevant file in the source code repository.
