postgresql duplicate key violates unique constraint

Question

Hi i have a question i know this was posted many times but i didn\'t find an answer to my problem. The problem is that i have a table and a column \"id\" i want it to be uni

Answer 1

On the first place, I thought the problem was the sequence :). But the error says ERROR: duplicate key value violates unique constraint "ndxregnum".. So I look for the name "ndxregnum" from my database. I found it under my table indexes. Then I delete "ndxregnum". Then error is gone. everything back to normal.

I hope this will help you...
