SELECT 
    (SELECT nspname FROM pg_namespace WHERE oid = pp.pronamespace) AS schemaname, 
    COALESCE((SELECT nspname||'.' FROM pg_namespace WHERE oid = pp.pronamespace AND nspname != 'public'), '')||proname AS full_name, 
    proname, pg_get_function_arguments(pp.oid) AS proargs, prosrc, procost, prorows, prosecdef, 
    pg_get_function_result(pp.oid) AS prorettype, 
    (SELECT lanname FROM pg_language WHERE oid = pp.prolang) AS prolang, 
    (CASE WHEN provolatile='v' THEN 'VOLATILE' WHEN provolatile='i' THEN 'IMMUTABLE' ELSE 'STABLE' END) AS volatility, 
    obj_description(pp.oid, 'pg_proc') AS description 
FROM pg_proc pp 
WHERE (SELECT nspname FROM pg_namespace WHERE oid = pp.pronamespace) = 'pg_catalog' 
    AND NOT pp.proisagg AND NOT pp.proiswindow 
ORDER BY proname, proargnames, proargtypes
