Looks great to me, pending a code examination. Will it also be possible to
query the SQLSTATE/ERRSTRING inside the EXCEPTION clause? i.e.
WHEN OTHERS THEN
RAISE NOTICE '%',sqlstate;
ROLLBACK;
That's something missing from 8.0 exception handling that makes it hard to
improve SPs with better error messages.
