But surely that would mean I couldn't do:

CREATE VIEW accts_schema.my_users AS
SELECT * FROM all_users WHERE dept='ACCTS';

CREATE VIEW sales_schema.my_users AS
SELECT * FROM all_users WHERE dept='SALES';

CREATE FUNCTION num_dept_users() RETURNS int4 AS '
SELECT count(*) FROM my_users;
' LANGUAGE SQL;

If SELECT num_dept_users() gives a different result to SELECT count(*) FROM
my_users that can't be desirable.
