Enhanced: 2.0.0 support for Polyhedral surfaces, Triangles and TIN was introduced. This method implements the OpenGIS Simple Features Implementation Specification for SQL 1.1. This method supports Circular Strings and Curves. PostGIS stores a table’s spatial information in geometry columns. Usually these columns have the word “geom” floating around in their name. If you select * on a table with a geometry column, the This function differs from GeometryType (geometry) in the case of the string and ST in front that is returned, as well as the fact that it will not indicate whether the geometry is measured. Enhanced: 2.0.0 support for Polyhedral surfaces was introduced.

The answers here may solve your problem, however if you already have postgis enabled on your DB, the issue may be that you are trying to restore a postgis table (with a geometry column) into a schema other than where your postgis extension is enabled. In pgAdmin you can click on the postgis extension and see which schema is specified.

In order for external programs to insert and retrieve useful geometries, they need to be converted into a format that other applications can understand.

In our last article 28 Sep 2018 PostGIS uses the “main” storage option for its geometry type. The main option tries to keep geometries in their original table until they get too 1 Aug 2018 PostGIS Performance Showdown: Geometry vs. Geography. Image.

Connect to your database with psql or PgAdmin. GEOMETRY and GEOGRAPHY are different PostgreSQL TYPES; exposed as higher level (SQL), user-defined composite types to the psql environment, but implemented as lower level (C) base types. These base types are defined on the C level with e.g.
