Yes , of course I must try to upgrade PGsql to 7.4 and may be  OS to FC 2-3 too.
My server products are intel based [mainboard , CPU ,Case , Power supply ,RAID
Network card] dual Xeon 32 bit 3.0 Ghz which I consulted Thai intel supervisor
and they told me that increasing the ram for more than 4 Gb. may be possible
depending on the OS.
I ask the programmer who wrote that huge query and they told me that it was the
query generated by Delphi 6.0 component and not written by themselve.
