Also, shared_buffers seem too low and work_mem too much high for your setup:
> shared_buffers = 1000
> work_mem = 131076
You should really raise shared_buffers and decrease work_mem: 1000
shared_buffers is probably too conservative. On the other hand 128MB per
sort could be eating your RAM quickly with 18 users connected.
