Greetings, one and all,

I have some very large memory bound queries being run in postgres.   
The documentation seems to say that I would be able to get more use  
out of the available memory if I were running the 64 bit postgres  
instead of the current 32 bit.  We have the binaries for both.  What  
would be the ramifications to changing from the 32 bit to the 64 bit  
process?

Thanks,
Carol
