Can you set both the log_rotation_age and log_rotation_size? If so, does either one have presidence over the other? I would like to have both on and am hoping that you will tell me that they work together.
So, if log_rotation_age = 1440, and log_rotation_size = 1048576 then my log will be rotated each time the log hits 1GB and also at the end of the day.
