Geodatabases in Microsoft Azure Database for PostgreSQL behave similarly to geodatabases in PostgreSQL with the following exceptions:
- You must use either the PostGIS Geometry or Geography data type for the spatial fields in your feature classes; ST_Geometry storage is not supported.
- The geodatabase administrator cannot drop client connections from ArcGIS Desktop apps.
- You cannot use the Create Database User geoprocessing tool to add users to the geodatabase.
Support for geodatabases in Azure Database for PostgreSQL starts at ArcGIS 10.6.1.
