[ADMIN] How to clear log files
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?

Re: [ADMIN] How to clear log files
What platform? If in Unix/Linux, just: cat /dev/null postgres_logfile orpostgres_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.

Actually, when you delete an opened file it isn't really deleted. Whatever program opened it can still read/write to it using the file descriptor. Is there a command that might clear a log file or force it to rotate? Truncating it like this should work: echo /path/to/logfile There's probably a better way though. -- Sent via pgsql-admin mailing list (pgsql-admin@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
