Hi,

 

How to keep log files only for 7 days

 

logrotate?  A bash script in a cron job? 

 

 

I think it is the default behaviour on default install:

 

1. Edit the postgresql.conf File:
2. Locate the postgresql.conf file for your PostgreSQL installation.
3. Configure the Following Parameters:
   1. Set log_filename to server_log.%a. This will create one log file per day named server_log.Mon, server_log.Tue, etc.
   2. Enable log_truncate_on_rotation to automatically overwrite last week’s log with this week’s log.
   3. Set log_rotation_age to 1440 (minutes), which corresponds to 24 hours. This ensures that logs are rotated daily.
4. Example Configuration:

 

log_filename = 'server_log.%a'

log_truncate_on_rotation = on

log_rotation_age = 1440

 

Still keep an eye on log_rotation_size

 

After making these changes, restart your PostgreSQL server for the new settings to take effect.
