Install the pg_bufferstats contrib module and take a look at how shared memory is being use. I like to use MRTG to graph shared buffer usage over time, but you can just do a SELECT count(*) WHERE NOT NULL to see how many buffers are actually in use.
Can you explain what you'd use as a diagnostic on this - I just installed the module - but I'm not entirely clear as to what the output is actually showing me and/or what would be considered good or bad.
