I haven't looked at the proposed patch, but I would've expected that it
duplicates the existing RESET ALL behavior for GUC settings. And that
already works the way you want. Values taken from the client connection
request packet establish the session defaults, ie, what RESET goes to.

Hmm. This seems a bit eye-of-the-beholder-ish, ie you could make a
legitimate argument either way. Maybe the RESET CONNECTION command
should have an option whether to zap prepared statements or not?
Is there anything else falling in the category of "debatable"?
