Doug Mitchell ([EMAIL PROTECTED]) reports a bug with a severity of 2
The lower the number the more severe it is.

Short Description
Duplicate records leaking into unique indexed tables 

Long Description

PostgreSQL 7.0.3 on RedHat 7.0

I have some fairly large (2-3 million rows) tables with a PRIMARY KEY that created a 
valid unique index.  After a few days of high-concurrency updates, vacuum says the it 
"can not insert a duplicate record into tablename_pkey".  I'm fairly sure that my 
application would crash if an INSERT failed due to key duplications, so I have to 
believe that this is internal to PG.  Maybe the index is pointing to both the current 
and a previous version of the same tuple.
I didn't see this until I upgraded from 7.0 to 7.0.3, but I was not looking for it.

Thanks,
Doug
