PostgreSQL 12
I just increased my work_mem to 24 MB. I cleared my statistics. I then went back later and saw the following:
Temporary files: 21
Size of temporary files 451 MB.
If you divide 451 by 21 you get 21.4 . I would have expected to see an average size greater than 24 MB. This implies to me that PostgreSQL is creating temp files that are smaller than 24 MB.
What am I not understanding?
