Our server manager seems to think that I have way to much memory. He
thinks that we only need 5 Gig.
You organisation probably spent more money getting your server manager to
investigate how much RAM you need
What Scott said ... seconded, all of it.
I'm running one 500GB database on a 64-bit, 8GB VMware virtual machine, with
2 vcores, PG 8.3.9 with shared_buffers set to 2GB, and it works great.
However, it's a modest workload, most of the database is archival for data
mining, and the "working set" for

The answer is "as much as needed to hold your entire database in
memory and a few gig left over for sorts and backends to play in."

This is actually normal. Look at the amount cached: 6257620K. That's
6.2Gig of cache. Linux is using only 6517776k - 6257620k of memory, the
rest is just acting as kernel cache. If anything tries to allocate a bit
of memory, linux will flush enough cache to give the memory to the
