Webhook Permissions Error Referring to Type in Extensions Schema

# Bug report If a web hook is set on a table where one of the types used in that table is defined in a separate schema e.g. `extensions`, an exception is raised Reproduction Steps: 1. Enable PostGIS extension in Studio in the `extensions schema` 2. Create a table with a Point type: `create table geom (coordinates extensions.geometry(Point, 4326))`; 2. Create am `insert` webhook for the `public.geom` table 3. Insert a row in the table ```sql insert into geom(coordinates) values(ST_GeomFromText('POINT(-71.060316 48.432044)', 4326)); ``` Error ``` permission denied for schema extensions ``` ---- The line in the `supabase_functions.http_request` that raises the exception is https://github.com/supabase/supabase/blob/aed59dd84f2a656dc5a7669b47bce8920d417d39/docker/volumes/db/webhooks.sql#L76-L82 You can confirm that by chopping everything else out of that trigger function and seeing that the issue persists ```sql CREATE OR REPLACE FUNCTION supabase_functions.http_request() RETURNS trigger LANGUAGE 'plpgsql' VOLATILE NOT LEAKPROOF SECURITY DEFINER SET search_path=supabase_functions AS $BODY$ BEGIN raise exception 'asdf %', current_role; perform jsonb_build_object( 'old_record', OLD, 'record', NEW, 'type', TG_OP, 'table', TG_TABLE_NAME, 'schema', TG_TABLE_SCHEMA ); RETURN NEW; END $BODY$; ```
