Re: Implementation of SQLSTATE and SQLERRM variables

This patch still needs work.

I think the docs need more than just "these variables are set when an
exception is raised".

The patch current resets SQLSTATE and SQLERRM whenever a new block is
entered. So:

create function trap_exceptions() returns void as $_$
begin
    begin
      raise exception 'first exception';
    exception when others then
      raise notice '% %', SQLSTATE, SQLERRM;
      begin
        raise notice '% %', SQLSTATE, SQLERRM;
      end;
    end;
    return;
end; $_$ language plpgsql;

The second RAISE will report "successful completion". Is this the
behavior we want?

Is SQLERRM the best name for that variable? It seems a little obscure to me.
