I've just run pgBadger on my pg logs and wonder if those checkpoint
statistics is something I should worry about or not?
The highest write time is about 47 minutes but I'm not sure if that's
checkpoint_completion_target*checkpoint_target value or real time between
sending the command to write and getting response?
If that's the first one - then I assume everything is ok because:checkpoint_timeout = 8mincheckpoint_completion_target
=0.9
but I'm not sure which value it is...
