Yes, you should start by tuning the server as a whole. Did you just
install the DB and restored your database? Have you tuned the config?

Tell us what are the basic performance-related parameters, i.e.

shared_buffers
effective_cache_size
checkpoint_segments
checkpoint_completion_target
work_mem
maintainance_work_mem
seq_page_cost
random_page_cost

and more information about the hardware and setup too (RAM, database size).

There's a quite nice guide regarding general tuning:
