Re: [HACKERS] Number of tuples (20300) not the same as heap (20301)

I see this problem all the time too. There are some scary bugs in the bowels
of the code that controls indexes and primary keys.

At this point, I have like 4000 duplicated primary keys, and I cannot update
sections of the table due to key violations.
