Hi, Firstly I will tell you what I'm trying to do: I have a database. I have a table Person. Person has location and this location need to be updated f.e. every 5 min or with higher frequently. Should I have some special tool, table or whatever to keep this data? I want to have history of location so I nned to keep old values. I'm a beginner so thank you for all advice :) -- View this message in context: http://postgresql.1045698.n5.nabble.com/Frequent-update-how-to-do-tp5737148.html Sent from the PostgreSQL - general mailing list archive at Nabble.com. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
