I didn't suggest making it mandatory - the current patch I attached is
completely opt-in (default setting is exactly how it works currently,
DBAs have to opt in by changing it).
My reasoning for making the warning the default is to encourage
extension developers to properly reserve GUC prefixes, without causing
compatibility problems for users - but I'm not sure about that, that's
why I submitted the patch with "off" default.
The fact users can set this to strict effectively makes variable registration mandatory for extension authors, not merely “encouragement”, IMO. That’s a decent step-up from “protect thyself” to “user-mandated”.
I’m just not seeing enough benefit here to provoke three-way discussions between users, extension authors, and ourselves. Rather leave well-enough alone given current information about the community’s experiences in this realm.
