I don't know a solution but I can say that I use successfully postgresql
since the 6.3, and I wanted to upgrade my 6.4.2 which worked very fine to
the 6.5.2 and I'd better have stayed in bed this morning... 

I havent yet tried to reduce the default shared memory usage with the -B
option. do you think this could significantly reduce the speed of the
database engine ?

thanks.
