The documentation says:
$ If the STRICT option is specified, the query must return exactly one
$ row or a run-time error will be reported
http://www.postgresql.org/docs/8.3/interactive/plpgsql-statements.html
In this case the query will always return one row. The row may have a
NULL if no matching values were found, but the row will be there.
select max(x) from (select generate_series(1,10) as x) y where x > 10;
max
-----
(1 row)
Not a bug.
