Morning all ...
Can someone explain to me how I should read this:
tablename | attname | avg_width | n_distinct
-------------------------+----------------------------+-----------+------------iwantu_pro_week | uid
| 8 | -1iwantu_pro_week | pro_week_agent | 9 |
9iwantu_pro_week | pro_week_time | 8 | -0.976321iwantu_pro_week | pro_week_post
| 5 | 2iwantu_pro_week | pro_week_club | 2 | 1
n_distinct, I'm taking it, of -1 means its a UNIQUE INDEX, and the
positive numbers are exact #'s ... but, -0.976321? :)
Also, how is the avg_width interpreted?
