The DECLARE has to go before the BEGIN:

CREATE OR REPLACE FUNCTION "public"."theo_test2" () RETURNS OPAQUE AS'
DECLARE  curr_theo cursor for select * from node_names;
BEGIN  fetch next from curr_theo;  close curr_theo;
END;
'LANGUAGE 'plpgsql' VOLATILE CALLED ON NULL INPUT SECURITY DEFINER;

I think you are missing an OPEN step too, and the FETCH syntax is wrong
for plpgsql.  Read the plpgsql doc section about using cursors --- it
is not at all identical to what you do in plain SQL.
