+-- 测试IMMUTABLE函数修复
+-- 运行此脚本检查函数是否正确创建为IMMUTABLE
+
+-- ===================================================================
+-- 1. 检查函数是否存在并且是IMMUTABLE
+-- ===================================================================
+
+SELECT 'Checking IMMUTABLE functions...' as status;
+
+-- 检查函数存在性和IMMUTABLE属性
+SELECT 
+    proname as function_name,
+    provolatile as volatility_code,

+-- 2. 测试函数功能
+-- ===================================================================

+-- 5. 最终验证
+-- ===================================================================
+
+SELECT 'Final verification...' as status;
+
+-- 再次检查索引
