I think you're confused about the scope of the exception block.
The syntax is

    BEGIN
      some code here that might throw an exception
    EXCEPTION
      some WHEN clauses here to catch exceptions from the covered code
    END

You wrote:

So this exception block can *only* trap errors arising from that one
RAISE command, not anything earlier in the procedure.  Seems unlikely
that's what you wanted.
