You can; just invoke the type object as in

psycopg2.NUMBER("12.34", None)

note that the second argument ought to be a cursor but you can safetly
pass None to almost all the typecasters except for the UNICODE one
because it needs some information about the encoding of the string and
will try to get it from cursor.connection.
