In the original coding of the log rotation stuff, we did not bother to make the truncation logic work for the very first rotation after postmaster start (or after a syslogger crash and restart). It just always appended in that case. It did not seem terribly important at the time, but we've recently had two separate complaints from people who expected it to work unsurprisingly. (Both users tend to restart the postmaster about as often as a log rotation is configured to happen, which is maybe not typical use, but still...) Since the initial log file is opened in the postmaster, fixing this requires passing down some more state to the syslogger child process. It's always been like this, so back-patch to all supported branches. |
