This patch locks down search_path in extension install and update scripts to only contain pg_catalog, this requires that any reference in those scripts is fully qualified. Additionally we add explicit create commands to all update scripts for objects added to the public schema. This change will make update scripts fail if a function with identical signature already exists when installing or upgrading instead reusing the existing object.

-- We started using CREATE OR REPLACE AGGREGATE for aggregate creation once the syntax was fully supported
