The following bug has been logged on the website:

Bug reference: 8891
Logged by: Anjali Arora

PostgreSQL version: 8.4.0
Operating system: CentOS 5
Description:

Hi all,

I have been using pg_dump/pg_restore to backup and restore the database in
our product for quite sometime.

One of our customers reported an issue with multiple entries for a field
marked as primary key.

After investigation of the logs we found the multiple entires were created
during pg_restore and the primary key constraint on the field could not be
created due to unique constraint violation.

Even on internet I came across the Postgres BUG 8382 & 7760 reported in the
past for this issue.

The Postgres version on which the issue was reported is 8.2.2

We have upgraded our Postgres version to 9.0.4 in the current product
release and I verified the issue fix information into postgres release notes
9.0.4, 9.0.15, and 9.1 but could not find anything related to this issue.

Please let me know in which release this issue got fixed.

Thanks,
Anjali
