See the following sections for information on how to do this. oracle_fdw — Has SDO_GEOMETRY to PostGIS geometry translation. Binaries available for windows and source for easy compile on Linux/Unix. Requires Oracle OCI.dll. Basic query to try to find matching SRID To check if one of the data was LineString, I try this query: SELECT count (id) FROM table_1 WHERE ST_GeometryType (polygon::geometry)='ST_LineString'; count ------- 0 (1 row) And to be sure I perform the same query on the logical geometry which should be there, and I get this : With spatial joins in PostGIS, the m ost typical functions are ST_In t ersects, St_DWithin, and ST_Contains. For ST_Intersects, you give two geometries as input. If any portion of geometry A intersects with geometry B, the function returns true.

This method implements the SQL/MM specification.

Mixed geometry are not supported ( neither are GeometryCollections?). So when using mixed geometries, you have to load 3 times the table each time selecting a different type of geometry .

In order for external programs to insert and retrieve useful geometries, they need to be converted into a format that other applications can understand. Fortunately, PostGIS supports emitting and consuming geometries in a large number of formats: 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. This function also indicates if the geometry is measured, by returning a string of the form 'POINTM'.
