I see, allowing @extschema@ in non-relocatable extension provides easy
way to shoot yourself in the foot.
However, it might be still useful to be able to distinguish extension
and core object in upgrade script of relocatable extensions. What
about (optional) way to set search_path to @extschema@, pg_catalog
instead of just @extschema@?
