I can't reproduce your problem:
test=# create table foo (a int, b int);
CREATE TABLE
test=# create or replace function get_foo() returns setof foo as $$begin return query select * from foo; return; end;
$$LANGUAGE 'plpgsql' VOLATILE;
CREATE FUNCTION
test=# select * from get_foo();
a | b
---+---
(0 rows)
test=# alter table foo add column c int;
ALTER TABLE
test=# select * from get_foo();
a | b | c
---+---+---
(0 rows)
(only if i drop a column):
test=# alter table foo drop column c;
ALTER TABLE
test=# select * from get_foo();
ERROR: structure of query does not match function result type
CONTEXT: PL/pgSQL function "get_foo" line 1 at RETURN QUERY
Please, provide us an example including the error you got.
