That's an exceedingly-weak argument for rejecting this patch. The
fact that you can probably hack around the lack of a hook for most
reasonable use cases is not an argument for having a hook that does
what people actually want to do.
When I first saw this thread, my initial thought of a use case is to prepare some key application queries so they are there and ready to go. That would need to be before the ExecutorStart_hook or ProcessUtility_hook if an app would just want to execute the prepared statement.
