i need to populate my table randomly with large amount of record in PostgresSQL like 200k

CREATE TABLE qr_code.tbl_transaction (
    transaction_id varchar NOT NULL,
    importo numeric NOT NULL,
    alias varchar NOT NULL,
    order_id varchar NOT NULL,
    filiale varchar NOT NULL,
    descrizione varchar NOT NULL,
    data_creazione timestamp NOT NULL,

    chiave_movimento_prenotata varchar NULL,
