maybe you can rewrite this to something else:
in the declare section declare a var
declare
var1 foo.id%TYPE;
[...and then in the begin section, where all code happens...]
select into var1 id from foo where x = "text";
if var1 is not null then
INSERT INTO foo2 (foo_id, foo2_text) VALUES (var1,"more_text")
else
INSERT INTO foo (text) VALUES ('text')
INSERT INTO foo2 (foo_id, foo2_text) VALUES (currval('seq'),
"more_text")
end if;
