Hi I want to ask some part of a question that is asked before by "Duan Ligong" and not answered
"
Could you explain how the clog files work roughly?
(What is inside of the clog files? when and how the new clog files
are created? when and in what case the old files are deleted
or rotated? how does postgresql regard a file is old enough to be
deleted? Does Vacuum will definitely cause deleting of old files
and creating of new clog files?)
"
Thansk for your interest
