Constructs the main module used to connect to a database for the given concurrency model.
module System : Caqti_driver_sig.System_unixmodule Pool : Caqti_pool_sig.S with type 'a future := 'a System.futureA pool implementation for the current concurrency library.

and type ('a, 'err) stream := ('a, 'err) Stream.tThe connection API specialized for the current concurrency library.
type connection = (module CONNECTION)Shortcut for the connection API passed as a value.
val connect :
