Hello Scott,

I am wondering how the query matters here?

Also, I am just running a simple select from "TEST" with COL1, COL2, COL3 in the WHERE condition.
select * from 'TEST" WHERE COL1='3456' AND  COL2='76542' AND COL3='5';

The actual Issue is I am unable to figure out why the table is having duplicate data in the primary key columns. Or how postgres accepted 2 rows with the same combination of the columns in the primary key constraint. I would expect it to throw primary key constraint violation error.

Regards,
Teja. J.

What query are you running?
