Scripting the creation of the ST_Geometry type in PostgreSQL
You can add the ST_Geometry type, subtype, and functions to your PostgreSQL database using a Python script that calls the Create Spatial Type geoprocessing tool.
The Create Spatial Type tool does the following:
- Creates an sde login role in the PostgreSQL database cluster
- Grants the sde user superuser privileges (these can be revoked after the ST_Geometry type is created)
- Creates a schema named sde in the database where you install the ST_Geometry type
- Grants the sde user full authority on the sde schema
- Grants USAGE privileges on the sde schema to the public login group (If you want, you can revoke this privilege, but you must grant USAGE on the sde schema to all users who need access to the ST_Geometry type, subtypes, or functions.)
- Creates the necessary functions, domains, tables (sde_coordinate_systems and sde_geometry_columns), and views (st_geometry_columns and st_spatial_references) in the sde schema, and the sde_spatial_references table in the public schema
Before running the script, you must copy the st_geometry library to the PostgreSQL server.
The following steps explain how to install the ST_Geometry type in a PostgreSQL database using a Python script:
Steps:
- Copy the st_geometry library from the DatabaseSupport directory in the ArcGIS client installation location and place it in the PostgreSQL lib directory.
- If PostgreSQL is installed on a Linux server, log in to the server as the root user and place the st_geometry.so file in the /usr/lib64/pgsql directory.
- If PostgreSQL is installed on a Windows server, place the st_geometry.dll file in the %PostgreSQL%\lib directory.

Copy this example script to the Python window in ArcGIS for Desktop, or to any Python IDE such as PythonWin or WING. Alter any variable values to match the information at your site.
