Great stuff.
My only gripe is the pattern where the identifier needs to be
re-installed when resetting the context. I don't think we need to hold
push for that reason alone, but I bet we'll be revisiting that.
I suppose this infrastructure can be used to implement the idea in
https://www.postgresql.org/message-id/CAMsr+YHii-BCC7ddpbb8fpCgzt0wMRt5GYZ0W_kD_Ft8rwWPiQ@mail.gmail.com
in some more acceptable manner. I'm not proposing it for now, just
parking the idea for a future patch.
