Create a new table from another Table without data and new primary key

Consider the following example:

CREATE TABLE incident
(
    sys_id int,
    f2 varchar(25)
);

-- Your way
CREATE TABLE incident_tag AS (SELECT * FROM "incident" WHERE 1=2);
ALTER TABLE incident_tag ADD CONSTRAINT incident_tag_pk PRIMARY KEY (sys_id) ENABLED;

-- Creating a table with LIKE replicates the source table definition and any storage policy associated with it. 
-- It does not copy table data or expressions on columns.
CREATE TABLE t2 LIKE incident INCLUDING PROJECTIONS;
ALTER TABLE t2 ADD CONSTRAINT t2_pk PRIMARY KEY (sys_id) ENABLED;

select export_tables('','incident');
                               export_tables
---------------------------------------------------------------------------
CREATE TABLE public.incident
(
    sys_id int,
    f2 varchar(25)
);

select export_tables('','incident_tag');
                                                                    export_tables
-----------------------------------------------------------------------------
CREATE TABLE public.incident_tag
(
    sys_id int NOT NULL,
    f2 varchar(25),
    CONSTRAINT incident_tag_pk PRIMARY KEY (sys_id) ENABLED
);

select export_tables('','t2');
                                                          export_tables
------------------------------------------------------------------------------
CREATE TABLE public.t2
(
    sys_id int NOT NULL,
    f2 varchar(25),
    CONSTRAINT t2_pk PRIMARY KEY (sys_id) ENABLED
);

Thanks a lot @mosheg
