TBH, I think this entire discussion has gone seriously off into the weeds. The original design where we just let a shared_preload_library function get into a hook is far superior to any of the overcomplicated kluges that are being discussed now. Something like this, for instance:
makes me positively ill. It introduces problems that we don't need, like how to parse out the sub-parts of the string, and the quoting/escaping issues that will come along with that; while from the user's perspective it replaces a simple and intellectually-coherent variable definition with an unintelligible mess.
