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.
Thanks,
David.
