That is certainly not going to work: that select does not produce an
array, it produces a column of user_t (of which SELECT INTO is only
gonna take the first, anyway).

Untested, but I think you'd have better results with

    _page.users := array(select users from users limit 10);

It'd also be smart to get rid of user_t and rely directly on the "users"
rowtype associated with the users table.
