Yes I'm using auto_increment (serial data type). No function, method inserts
PK's anywhere in my code. I'm thinking/guessing it had something to do with
vacumn or the backup. I have been using Postgres for a number of years now
and I never seen this in the past. So I'm really at a loss as how this could
have occurred. The backup is a windows product "exec" and I'm using a
special plug-in from exec for the Linux backup. But I still can't see this
actually happening.
Well I have it running for the moment and I'll have to account black magic as
the cause.
