In looking at top, I have noticed when doing some
long queries that RAM memory is only being used
at 1-3%. While, CPU often jumps to 97, 98, even
99% utilization (which is great!).
Is this normal for RAM utilization?
If not, how can I better utilize my RAM during
queries and or general processing?
Thanks for your help!

It depends on what you have set shared_buffers to in your
postgresql.conf file. If you have not tuned this value yet you should
do so as the default setting is very conservative.
There is a lot of discussion on appropriate shared_buffers settings if
you search the mailing list archives...

What is better for holding small numbers in a program?
I know that char uses less memory, but, with 32 or 64 bits systems,
there are advantages (such as processing time) in using int instead of

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

For most users, this new feature is actually very convenient. If you want to control the update process,...
