EG: 'ST_LineString', 'ST_Polygon','ST_MultiPolygon' etc. 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.

Often used to return the 2d enclosing box of a geometry. box3d A box composed of x min, ymin, zmin, xmax, ymax, zmax. Often used to return the 3d extent of a geometry or collection of geometries. Once the event subscriber is registered, you can use the column types geometry and geography in your property mappings (please read the PostGIS docs to understand the difference between these two types).
Returns the type of the geometry as a string. EG: 'ST_LineString', 'ST_Polygon','ST_MultiPolygon' etc. 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 … Description. geometry is a fundamental PostGIS spatial data type used to represent a feature in planar (Euclidean) coordinate systems..
Returns the type of the geometry as a string.
What I found a merely cosmetic thing until now started to bother me more than I liked: the QGIS dialog for adding PostGIS layers lists many layers twice, once with geometry column, geometry type and reference system pre-selected, once with input fields for manually specifying them.
To use the PostGIS geometry or geography type, install PostGIS on the PostgreSQL database cluster. Once installed, either use the PostGIS template database to create a database containing the PostGIS types, or configure an existing database to use the PostGIS types.
Postgis geometry type = Geometry. Simply I've got a number of PostGIS layers that have a geometry type of Geometry, as a posed to point, line, polygon. QGIS 2.0+ doesn't like this very much and wants me to set the geometry type and in general makes my PostGIS connect in QGIS slow.

Description. geometry is a fundamental PostGIS spatial data type used to represent a feature in planar (Euclidean) coordinate systems.. All spatial operations on geometry use the units of the Spatial Reference System the geometry is in.

Most PostGIS functions are built to use the planar "geometry" type, and you will have to cast your data to use them. Geography calculations on the sphere are quite expensive, for big queries you'll find a noticeable performance penalty.
2-dimensional Points must have Z=0.0, as well as non-measured Points must have m=0.0. PostGIS also has a geography data type, which provides native support for spatial features represented on "geographic" coordinates (sometimes called "geodetic" coordinates, or "lat/lon", or "lon/lat"). But you can also work with “lat/lon” data using the normal geometry data type. A column storing Geometry information. It is only available in PostgreSQL (with PostGIS), MariaDB or MySQL. GeoJSON is accepted as input and returned as output.
