By way of feature ideas, one very convenient but not widely used feature of
Apache's log rotator is the ability to specify a strftime() format string
for the file extension. For example, if I want to have my logs rollover
every 24 hours and be named log.Mon, log.Tue, log.Wed, I say something like

pg_ctl start | rotatelogs 86400 "%a"

This causes the logs to overwrite themselves every seven days, taking log
maintenance time to very near zero. We also customized our use of it to
allow us to automatically move existing logs out of the way to "log.1",
"log.2", or to simply overwrite existing logs.
