No, it's not possible to do the above. This is a flaw in the current
implementation of PL/pgSQL that will not be resolved until we attract
some new Postgres hackers who really care about upgrading PL/pgSQL.
Currently, if you want to use an array, it has to be passed as a
parameter, or come from an external table. You cannot declare an
Array data type. Annoying, really.
