Обсуждение: Table Statistics with pgAdmin III
I have installed pgAdmin III 1.6. In the tool when you click on a particular table you can select a tab called “Statistics”. This tab has all kinds of info on your table. For some reason the only info I see is for table size, toast table size and indexes size. Is there a reason that the other 15 fields have zeros in them? I was thinking that maybe I needed to turn on a setting within my database in order to get statistics reported.
Thanks,

Whatvalues are at zero? Regards, Dave
All of the fields are zero except for the three I listed in my posting.
