You want to store rows with an object id, a field or fields storing the hour and the 8 object fields (assuming these fields shouldn't also be one per row - but without any more knowledge about them I can't say). You should put a primary key constraint on the object id and the hour field(s). > > Or may be it's not good idea to use postgres for this purpose? Without seeing what you are going to do with the data it is hard to say if using a dbms is overkill or not. ---------------------------(end of broadcast)--------------------------- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
