(** PostgreSQL driver for Caqti based on pgx

    This driver is implemented in terms of the pgx library.

    It handles URIs of the form
    {[
      pgx://<user>:<password>@<host-or-directory>:<port>/<database>
    ]}
    where [<host-or-directory>] is either a host name, an IP number, or a
    directory containing the Unix domain socket of a locally running PostgreSQL
    server.  In the latter case, the directory must be percent-encoded, e.g.
    {[
      pgx://jdoe@%2fvar%2frun%2fpostgresql
    ]}

    The interface provided by this module {e should normally not be used by
    applications}, but provides access to some pgx specifics in case they are
    needed. *)
