When I ment memory allocation, I look with htop to see the process list, CPU 
load, memory, swap. So I didn't ment the a postgre process uses that amount 
of memory.

I read some tuning things, I made the things that are written there, but I 
think that there improvements can be made.

regards,
Andy.
