See PostGIS documentation You can specify a keyword to use the PostGIS geometry type when you create feature classes in ArcGIS. You can also use SQL to create spatial tables with PostGIS columns, then access them from ArcGIS or register them with the geodatabase. Geometry data types. As indicated in the table, ArcGIS creates and can work with three spatial data types in PostgreSQL: Esri ST_Geometry, PostGIS geometry, and PostGIS geography. The next two sections provide more background on these data types. ST_Geometry.

select a, st_union(geom) from table group by a srid: 25832, geometry type: Multipolygon. The view has no SRID and the geometry type is "GEOMETRY". Now i want If you mean the new GM 2016 PostGIS data server, it does not distinguish between geometry types and stores all as one generic type "GEOMETRY". So if your geometry type is restricted to MULTIPOLYGON, it is possibly the reason why the table is read only. Another reason might be missing the ctid column (table with oids = false). Geometry.

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. PostGIS Geometry Types PostGIS Geometry Types. In the last section, we worked with a table – usa.states – containing geometries of the type A. Create a new empty spatial table. In the Browser pane within pgAdmin, right-click on the Schemas node beneath the B. Add rows to the spatial table. In geodatabases in PostgreSQL, this can be set to either ST_GEOMETRY or PG_GEOMETRY (the setting for the PostGIS geometry type).

In the Browser pane within pgAdmin, right-click on the Schemas node beneath the B. Add rows to the spatial table. In geodatabases in PostgreSQL, this can be set to either ST_GEOMETRY or PG_GEOMETRY (the setting for the PostGIS geometry type). Therefore, when you want to create a feature class using ArcGIS that uses the PostGIS geometry type, specify a configuration keyword that contains the GEOMETRY_STORAGE parameter set to PG_GEOMETRY. But PostGIS supports additional dimensions on all geometry types, a “Z” dimension to add height information and a “M” dimension for additional dimensional information (commonly time, or road-mile, or upstream-distance information) for each coordinate. For 3-D and 4-D geometries, the extra dimensions are added as extra coordinates for each vertex in the geometry, and the geometry type is enhanced to indicate how to interpret the extra dimensions. 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.

The geometry_columns view takes care to remove any Z/M suffixes.
