oki, Thanks for the information. I have a look at 8.0 beta, but cannot start the statistic collector. (I had post this err message before for help, but havent really got any clue to fix it) > LOG: could not create IPv6 socket: Address family not > supported by protocol > LOG: could not bind socket for statistics collector: > Cannot assign requested address > LOG: disabling statistics collector for lack of > working socket btw, what i want to ask here is does postgreSQL have any kind of read-ahead buffer implemented? 'cos it would be useful in multimedia case when we always scan the large table for continous data. Thanks Ho __________________________________ Do you Yahoo!? New and Improved Yahoo!
