I have a similar system.  It's a dual PII-450MHz Xeon with 512MB of RAM
running RH7.1 and 7.1.2.  As far as performance tuning goes, here's the
relevant lines from the postgresql.conf file we're using:

  max_connections = 64 # 1-1024
  sort_mem = 8192
  shared_buffers = 192
  fsync = false

Obviously, depending on your needs, you can adjust those.  If you've
got a 1GB of RAM, I'd set everything high and not worry about it.
