Cockroachdb v0.2.2 connector does not transfer constraints and foreighn keys to PsotgresDB

[TheScar1488]

Hello.
I'm using Cockroachdb v0.2.2 connector transfering schema+data to PostgresDB (Postgres v2.4.0 connector).
In destination DDL there is no constraints and foreighb keys for table.
Example:
(show create all tables in cocroach sql to get table DDL)
CCDB:

CREATE TABLE public.orders (
        order_id UUID NOT NULL,
        user_id UUID NOT NULL,
        shipping VARCHAR(40) NOT NULL,
        amount DECIMAL(19,2) NOT NULL,
        currency VARCHAR(3) NOT NULL,
        first_name VARCHAR(255) NULL,
        last_name VARCHAR(255) NULL,
        phone_number VARCHAR(40) NULL,
        created_at TIMESTAMP NULL,
        updated_at TIMESTAMP NULL,
        payment_url VARCHAR(512) NULL,
        status VARCHAR(100) NULL,
        payment_method VARCHAR(100) NULL,
        country_code VARCHAR(2) NULL,
        email VARCHAR NULL,
        language VARCHAR(2) NOT NULL DEFAULT 'EN':::STRING,
        billing_email_address VARCHAR(255) NULL,
        client_type VARCHAR NOT NULL DEFAULT 'web':::STRING,
        amount_refund DECIMAL(19,2) NULL,
        used_points INT8 NULL,
        bonuses DECIMAL(19,2) NULL,
        CONSTRAINT "pk-order" PRIMARY KEY (order_id ASC),
        INDEX "ix-order_id_user_id" (order_id ASC, user_id ASC)
);

In PostgresDB after transfer:

CREATE TABLE public.orders (
	email varchar NULL,
	amount numeric(38, 9) NULL,
	status varchar NULL,
	bonuses numeric(38, 9) NULL,
	user_id varchar NULL,
	currency varchar NULL,
	"language" varchar NULL,
	order_id varchar NULL,
	shipping varchar NULL,
	last_name varchar NULL,
	created_at varchar NULL,
	first_name varchar NULL,
	updated_at varchar NULL,
	client_type varchar NULL,
	payment_url varchar NULL,
	used_points int8 NULL,
	country_code varchar NULL,
	phone_number varchar NULL,
	amount_refund numeric(38, 9) NULL,
	payment_method varchar NULL,
	billing_email_address varchar NULL,
	"_airbyte_raw_id" varchar(36) NOT NULL,
	"_airbyte_extracted_at" timestamptz NOT NULL,
	"_airbyte_generation_id" int8 NULL,
	"_airbyte_meta" jsonb NOT NULL
);
CREATE INDEX orders_airbyte_tmp__airbyte_extracted_at_idx ON public.orders USING btree (_airbyte_extracted_at);
CREATE INDEX orders_airbyte_tmp__airbyte_raw_id_idx ON public.orders USING btree (_airbyte_raw_id);

and no SEQUENCE was created.
