I am new in PostgreSQL and I did the following. I removed around 3 out of 5 million records from one table and then I did vacuum analyze, then I checked that table in pg admin the estimate row count was 13 million instead of 2 millions that it must be. Why is that? I did this records removal to free up some space but instead my space was limited even more. What can I do to overcome this problem?
Thanks in advance
