Right. It seems to me that ROUTINE_NAME is vastly less compelling than
the fields that are likely to be present in the committed patch. GET
DIAGNOSTICS, as implemented by DB2, allows clients /to poll/ for a
large number of fields. I'm not really interested in that myelf, but
if we were to add something in the same spirit, I think that extending
errdata to support this would not be a sensible approach.

Perhaps I'm mistaken, but I can't imagine that it would be terribly
useful to anyone (including Pavel) to have a GET DIAGNOSTICS style
ROUTINE_NAME.
