I disagree.
It is arguable whether having

should give an error for a Databases type hint on the first parameter,
as it can be converted (that's a soft vs strict typing issue).
However, such typehint should avoid a call like:
> database_select(1024, $sql);
with which the function can't do anything sensible with (other than
returning an error if it does its own checking).
