>>>>>>>>>>>>>>>>>>>>  Question <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
>
>   there are two case in the buffer management of O/S.
>
>   first, the database system reserves part of main memory to serve as 
>   a buffer which it, not the operating system, manages.
>
>   second, the database system implements its bufer within the virtual 
>   memory of the operationg system. the database itself is stored in
>   the operating system's file system.
>
>   i wonder if postgres is this case or that.       
>   and i want to know the reason.
>
>   thanks.
