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.
