Hello team I hope everything going well for you guys!
I have a question about log rotation.
I set the parameters as a daily. The set parameters are as follows.
In this case, the log file is created as "postgresqllogtest-2023-12-12_182351.log" after the 13th day file, the logs in the 12th day file need to be truncated.
Is the expected result correct? Or does PostgreSQL not support deleting, truncating files? I got successful results when I did this process hourly. However, I could not get a correct result when I tried it daily log truncate.
The parameter for I used as Hour log; postgresql-%H%M
log_destination = 'stderr'
logging_collector = on
log_directory = '/var/log/postgresql/logtest'
log_filename = 'postgresqllogtest-%Y-%m-%d_%H%M%S.log'
log_rotation_age=1440
log_min_duration_statement = 5000
log_line_prefix = 'time=%t [%p]: db=%d,user=%u,app=%a,client=%h '
log_statement = 'none'
log_temp_files = 0
log_timezone = 'Europe/Istanbul'
log_hostname = on
log_min_messages = warning
log_min_error_statement = error
log_lock_waits = on
