Is there a way for me to tell postgres to clear the log file. Example: I have log files created with names corresponding to the days of the week. This way they overwrite each other every week. When I deploy software enhancements I would like to clear the log file for the day without having to stop postgres. This way anything I see I know was after the deployment of my enhancements. I tried to just delete the file with postgres running. I found that it did not recreate the log file so I was forced to restart postgres.
Is there a command that might clear a log file or force it to rotate?
You should be able to set 'log_truncate_on_rotation=on' in postgresql.conf and then run:
select pg_rotate_logfile();
That should rotate it, and if you have your log_filename setup with day of week only, it should truncate and restart in the same logfile. Haven't tested it, so I may be wrong, but it's worth a shot.
