Save the Date.now () no postgres
Hello, I would like to know what type of data I use in the time column of my table, which will store the Date.now() of Javascript, it returns an integer like this 1591181717431. I thought about using big int, does anyone have a better idea?

This integer is the amount of milliseconds that have passed from the date of 01/01/1970 to 00:00:00 to the current moment. Formally known as was Unix .
Postgres is able to convert an integer representing the Unix Era in seconds to type TIMESTAMP by means of the function to_timestamp(), see only:
CREATE TABLE tb_foobar
(
id INTEGER,
datahora TIMESTAMP
);
INSERT INTO tb_foobar (id, datahora) VALUES (1, to_timestamp(1591181717431 / 1000));
INSERT INTO tb_foobar (id, datahora) VALUES (2, to_timestamp(1591182735732 / 1000));
INSERT INTO tb_foobar (id, datahora) VALUES (3, to_timestamp(1581182718337 / 1000));
Querying Table:
SELECT id, datahora FROM tb_foobar;
Output:
| id | datahora |
|----|----------------------|
| 1 | 2020-06-03T10:55:17Z |
| 2 | 2020-06-03T11:12:15Z |
| 3 | 2020-02-08T17:25:18Z |

Use
new Date().toLocaleString();
But I recommend that if you want to save the date that the record is entered in the bank, I would do like this:
alter table tabela alter column datahora set default current_date;
That way every time you enter a record it will take the time and date of the system and save in the record
