It is default value ( #checkpoint_segments = 3 # in logfile segments, min
1, 16MB each )
Many of my database configurations are default values. (plain TOAST etc)
my database is a log database so, some tables of db grow everytime.
My ' /base ' directory contains a lot of compressed object (1GB size)
These are maybe normal operations but I don't understand that
although I delete many rows from my db and regularly vacuum , reindexing
operations,
how doesn't postgresql give back that deleted areas for reusing.
