Subject: Unique key constraint Issue
Date: Mon, 25 Nov 2024 12:00:55 +0530
Message-ID: <CAH=zU4t3KRpt6uTZn_4eKkvpL_X9ACGNZ+XDxfMjnn6ovAyPVQ@mail.gmail.com> (raw)

Hello,

We have postgresql servers with PostgreSQL 13.10   on Ubuntu release 22.04.

The issue is a unique key constraint with two columns one is character
another is integer. At some point the unique key did not work as I see
duplicate values with these two columns combination and it happened on
multiple servers on multiple databases on same table with same unique key.
I tried db dump and restore but the key is failing to create when restore
with duplicate value errors.
