src/pl/plpgsql/src/plerrcodes.h contains the following comment:
/* Success and warnings can't be caught, so omit them from table */
Maybe an IF NOT FOUND test could substitute for trapping NO DATA.
As for SUCCESSFUL COMPLETION, it seems reasonable to infer that the
operation was successful if an exception *isn't* raised (for some
definition of "successful" -- additional logic might be necessary).
Or maybe I'm misunderstanding the purpose of trapping these conditions.
