I’ve created a Managed PostgreSQL Database with the Postgis extension. It creates the spatialrefsys table with the list of supported reference projections for spatial queries. I need to add a new projection to spatialrefsys but it gives the error: permission denied for table spatialrefsys. I’ve used the doadmin user to create the extension and the table spatialrefsys is owned by postgres user. I can’t change the ownership, neither the permissions. How can I do that with my user privileges?

Thanks
