Make the following changes to postgresql.conf:

autovacuum = on                 # enable autovacuum subprocess?
autovacuum_vacuum_threshold = 500       # min # of tuple updates before
                                        # vacuum
autovacuum_analyze_threshold = 200      # min # of tuple updates before
autovacuum_vacuum_scale_factor = 0.2    # fraction of rel size before
                                        # vacuum
autovacuum_analyze_scale_factor = 0.1   # fraction of rel size before
