You don't need to use a bigint, read the documentation on data types.
There are a number of different things you can use for a timestamp, here
are a few :
abstime
abstime with timezone
timestamp
timestamp with timezone
Then when you are inserting your data, you can use 'now' as the time.
Eg.
CREATE TABLE pointy_stuff (
PointId integer,
PointName varchar(50),
PointType integer,
CreateTime abstime
);
INSERT INTO pointy_stuff (
PointId,
PointName,
PointType,
CreateTime
) VALUES (
'12345',
'point1',
'1',
'now'
);
I believe abstime is the smallest timestamp, but I could be wrong.
To output the data as a bigint I believe you can use this.
SELECT
PointId,
PointName,
PointType,
date_part('epoch',CreateTime) as unix_ts
FROM
pointy_stuff
;
Hope that helps.
