this is how I do it if this helps:
column_name timestamp without time zone NOT NULL DEFAULT
('now'::text)::timestamp(6) without time zone

Subject: [GENERAL] Updating column on row update
Hi,
This should be simple, but for some reason I'm not quite sure what the
solution is. I want to be able to update the value of a column for rows
that have been updated. More specifically, if a row is updated, I want it's
modified_date column to be populated with the current time stamp. I've
looked at triggers and rules, and it looks like I'd need to create a
function just to achieve this which seems incredibly clumsy and unnecessary.
Could someone enlighten me?
Thanks
Thom
