I run postgres as a service with cygrunsrv. According to cygrunsrv's README, it may one day be able to pipe stdout/stderr. But not yet. So if you do a standard installation, /var/log/postmaster.log grows indefinitely. Here is a way to renew the log file regularly: - get the rotatelogs component from the apache package: . download the apache package with setup.exe . copy release\apache\apache-<version>.tar.bz2 in /tmp . cd / . tar -jxf /tmp/apache*.bz2 usr/share/man/man8/rotatelogs.8 usr/sbin/rotatelogs.exe - change some parameters of cygrunsrv --install or directly change them in the registry (HKLM\System\CurrentControlSet\Services\postmaster) �-path /usr/bin/bash.exe --args "--login -c \'/usr/local/pgsql/bin/postmaster -D /usr/share/pgsql/data �i -c log_timestamp=1 2>&1 | /usr/sbin/rotatelogs /var/log/pgsql 604800\'" Notes: - I run a 7.3.6 version, so you may have to adjust the paths to postmaster and data to different new settings. - I'm used to set --login when I run a bash. Didn't check if it's really mandatory here. - 604800 means a week in seconds. It seems to work fine. But one minor defect is that these 3 lines do not appear in the log when the service is stopped: <datetime> LOG: fast shutdown request <datetime> LOG: shutting down <datetime> LOG: database system is shut down I guess that rotatelogs.exe is terminated even before to get the last output of postgres.exe. Any idea to improve this last point? [Jason, As a user, I would have been happy to find such directions in the README file, at least as a suggested example. Of course, it's up to you.] __________________________________ Do you Yahoo!? Vote for the stars of Yahoo!'s next ad campaign! http://advision.webevents.yahoo.com/yahoo/votelifeengine/
