Setar auto-increment in DBeaver

After creating the idpagamentoCielo column as the primary key, I was not able to add the auto-increment property to the column.

How can I assign the auto-increment property to the idpagamentoCielo column?

Note: the database is postgresql

Automatic generation SQL :

CREATE TABLE public.pagamentocielo (
    idpagamentocielo int NOT NULL,
    CONSTRAINT pagamentocielo_pk PRIMARY KEY (idpagamentocielo)
)
WITH (
    OIDS=FALSE
);
