[ shrug... ] The complaints I've heard about the errcontext mechanism
are that it's too verbose already. I can't see a good use-case for the
above, and I do know that a lot of people wouldn't consider it an
"enhancement" at all.
I suspect the problems you wish to solve would be better addressed by
using the plpgsql debugger that will be available with 8.2. It sounds
to me like you are wishing for a debugger stack trace, and if you need
one of those you probably need other debugger facilities too.
