Yeah, this is a good point.  I'm willing to concede that we are not
close to having a uniform API that could be used for checker functions,
so maybe what we should do for now is just invent
plpgsql_check_function(regprocedure).  I'd still like to see the
question revisited sometime in the future, but it would be appropriate
to have a few working examples of popular checker functions for
different languages before we try to invent a common API.
