I have a lot of entries like this in the log file 2011-11-17 02:02:46 PYST LOG: checkpoints are occurring too frequently (13 seconds apart) 2011-11-17 02:02:46 PYST HINT: Consider increasing the configuration parameter "checkpoint_segments". No, checkpoint parameters in postgres.conf are: checkpoint_segments = 32 # in logfile segments, min 1, 16MB each checkpoint_timeout = 10min # range 30s-1h checkpoint_completion_target = 0.9 # checkpoint target duration, 0.0 - 1.0 What should be a correct value for checkpoint_segments to avoid excessive checkpoint events? |
