module type CONNECTION = CONNECTION with type 'a io = 'a ioval connect : Uri.t -> (module CONNECTION) ioEstablish a single connection to a database. This must only be used by one thread at a time, cooperative or not.
val connect_pool : ?max_size:int -> Uri.t -> (module CONNECTION) Pool.tCreate a pool of connections which can be shared among multiple cooperative threads run from the main system thread.
