That isn't an adequate reason for pushing an implementation detail into
the user's face.  IMHO no error message seen by ordinary users should
mention OIDs at all.  A thought experiment: what would you do with the
message if we were to reimplement the system to not use OIDs?

I'm willing to talk about putting a complete specification of the
function (with schema and arg types) into the context line, but you
haven't really made the case why that wouldn't be just clutter for most
