2021-09-30 - Version 3.2

This release is a maintenance release that fixes issues reported since previous release. It also adds new reports and features.

  • Add STATS_REPORT_OUTDIR configuration directive to pgcluu.conf to set the directory where the pgCluu reports will be saved. Default to /var/lib/pgcluu/report/.
  • Add command line option -t | --lock-timeout with default to 3 seconds to self terminate a SQL query that could be lock by the activity of an other session like a drop table for example.
  • Add collect and report of unused trigger functions.
  • Add system statistics dedicated to PostgreSQL process through stats reported by pidstat.
  • Add report of CPU scaling_governor to check if it set to powersave, setting it to performances can improve performances up to 20% following the PostgreSQL load. For more information on this kernel parameter see https://wiki.archlinux.org/index.php/CPU_frequency_scaling#Scaling_governors

Backward compatibility:

  • Change default retention time to 30 days instead of no storage limit to avoid possible out of memory on uncontrolled installation.
