libpq has several internal uses of the error-field codes that perhaps
ought to be converted to use these macros, eg, pqInternalNotice(),
pqGetErrorNotice2(), pqGetErrorNotice3().

More generally, is libpq the right place to declare these?  Shouldn't
we instead put 'em in postgres_ext.h, and teach the backend code to use
'em too?
