Thread: loading data into postgresql became slow after i used VACUUME command.
dear sir,
i used to load 70 Mb flatfile data into postgresql database in less than 1 hour with my java code. two days back i gave VACUUME command and deleted all records with TRUNCATE command. now it is taking more than 3 hours to load same flatfile with same java programme.
why it is so? and what to do to make it fast?
i am using postgresql 7.2.1 in red hat linux 7.1
thanks in advance,

Consider upgrading to 7.4.x, 7.2.1 is quite old now. Dave On Mon, 2004-04-26 at 13:15, Uwe C.
