Thanks.

I played with this for a couple of hours, and the inevitable conclusion
is that this approach is doomed, if only because it depends on the user
not setting a non-english locale. Otherwise errcontext() would store
translated messages in the error stack, and the code trying to parse
them would fail miserably.

I haven't looked at pldebugger, but if it does anything similar to this,
it's obviously prey to the same problem ... which I guess means that we
really need some more robust way of doing it, there already being three
potential users of it.
