Hi,
    Is there some kind of command or internal PostgreSql
column to find out when a table was last changed (INSERT, UPDATE
or DELETE) on a 7.0.2 Server ?

thanks,
    Markus

No u need to maintain this information in another column such as
last_update_date which your application should update everyt time u
perform any operation on it..

Hope this helps

Better yet, define a trigger so you and/or other programmers don't have
to worry about including that field in every update.
