PostGIS extension not installed on Postgres 17

-- Failed query:
-- CREATE EXTENSION IF NOT EXISTS postgis;
-- Query can't be composed effectively.
-- The PostGIS extension is not installed on this database. The query to create the extension cannot be fixed without first installing PostGIS on the database server. This typically requires administrative privileges and cannot be done through a simple SQL query. You would need to contact your database administrator or hosting provider to install the PostGIS extension on the server before you can create it in your database.
