Thanks for answering.
This is my configuration:
# - Memory -

shared_buffers = 1000        # min 16, at least max_connections*2, 8KB each
#work_mem = 1024        # min 64, size in KB
#maintenance_work_mem = 16384    # min 1024, size in KB
#max_stack_depth = 2048        # min 100, size in KB

The PC where we are runing PostgreSQL server is:
AMD Athlon(tm) 64 Processor
3000+
1.79 GHz, 1.93 GB RAM
with WindowsXP Proffesional, Version 2002 Service Pack 2.

How should we set it?

Shared buffers even on a workstation should be higher than 1000 if you want some performance.  It depends how much memory you have spare to use for PostgreSQL.  But something like
shared_buffers = 20000
maintenance_work_mem = 256000

Will certainly give you a performance boost.  You will have to adjust those figures based on whatever else you are doing on the machine.

Thanks a lot!

maintenance_work_mem is the thing to look at, actually. I concur that
bumping it up might help.
