Bind iterator

[LazyMechanic]

Hello.

I need to bind some collection into sql (t.cid = ANY($1)) which is not an array (tree) and for which it is expensive to create a vector for insertion each time.

I found #3651, but I can't implement this functionality for myself without patching sqlx itself because of private functions and structures (.patch_type_by_name(), ...).

Is there a way to implement Encode trait for my custom iteratable collection without creating a temporary array/vec?
