Description
Registering pgstat_function_wrapper_hook to call pgstat_init_function_usage_no_drop for Babelfish, bypassing the engine's pgstat_init_function_usage. This eliminates the pgstat_drop_entry call that causes a double-drop crash when multiple sessions concurrently DROP, CREATE, and EXEC the same procedure.
