I think this is a matter to be solved at the level of the API of each
client library. For example, libpq's PQerrorMessage would presumably
construct some unified string out of these three fields and the error
severity; plus we'd add new calls to extract the individual fields.
I do not think it's appropriate to try to control this from the server
side of things.

Some GUC variables would do for that, probably, if we think it's a good
idea to be selective (a proposition I'm dubious about).
