odd, the task bar doesn't show any sort of memory utilization on any of
my windows systems.    are you referring instead to the Task Manager ?

Note the Windows Task Manager by default doesn't show shared memory
resources either, you'd have to go to the 'details...' view, then add a
column for 'Memory (shared working set)' to see this.

also note, the 'working set' is the memory thats actually being used,
not potentially allocated.   so even if you've told PG it can have 10GB
of shared buffers, if your database accesses since restarting the
database server have only touched 2GB of actual data, thats all that can
be 'working set'
