What platform?  If in Unix/Linux, just:

 

 cat /dev/null > postgres_logfile

 

or                   > postgres_logfile

 

Most running programs don’t like it when you delete a file with an open file handle but you it doesn’t mind if you clear it on the fly.  Not sure how to do this in a Windows environment.

PostgreSql:8.4.1

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?

 

Thanks,
