Thanks a lot Tomas for the reply. Which version are you running, exactly? Whih minor version? [Pawan]: Its (PostgreSQL) 9.5.9
sai=> select version(); version ---------------------------------------------------------------------------------------------------------- PostgreSQL 9.5.9 on x86_64-pc-linux-gnu, compiled by gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-11), 64-bit (1 row) Why do you think it's the issue you linked? [Pawan]: Because the thread which I shared also has problem statement like "Duplicate entries of Primary key" . If this is also known to this version, I will be appreciating a lot if we have some Workaround or config change. In our production: See below entries, proc_id is primary key and we can see duplicate entries. How it is possible? sai=> select ctid,proc_id from etl_status where proc_id='2993229'; ctid | proc_id ----------+--------- (381,20) | 2993229 (388,28) | 2993229 (2 rows) Any idea, how it happened? I will waiting for your reply WBR, -Pawan -----Original Message----- From: Tomas Vondra <tomas.von...@2ndquadrant.com> Sent: Thursday, July 04, 2019 10:18 PM To: Kumar, Pawan (Nokia - IN/Bangalore) <pawan.ku...@nokia.com> Cc: and...@2ndquadrant.com; and...@dunslane.net; j...@agliodbs.com; pgsql-hack...@postgresql.org Subject: Re: duplicate key entries for primary key -- need urgent help On Thu, Jul 04, 2019 at 01:37:01PM +0000, Kumar, Pawan (Nokia - IN/Bangalore) wrote: >Hi Guys, > >Can you please help here? > >Below reported issue in past about duplicate key entries for primary key. >https://www.postgresql.org/message-id/534c8b33.9050...@pgexperts.com > >the solution was provided in 9.3 version of postgres but it seems issue is >still there in 9.5 version which I am running currently. > >Can you please let me know if this is also known in 9.5? any fix or Workaround >please? > Which version are you running, exactly?
