It should be easy to do using the ProcessUtility_hook hook, defined in
a custom module written in C. As long as your module is preloaded
(one of the *_preload_libraries GUC), your code will be called without
the need for any SQL-level object and you would be free to add any
custom GUC you want to enable it on a per-user basis or anything else.
