Hi Team, We have successfully configured and tested Logical Replication between Publisher and Subscriber. But on the Subscriber side we are getting generated a number of error log files(around 20-30 GB). The most common log messages found in the log(/var/log/postgresql/abc.log) are: 2018-08-26 06:32:09.659 IST [9385] ERROR: duplicate key value violates unique constraint "table_pkey" 2018-08-26 06:32:09.637 IST [13919] LOG: worker process: logical replication worker for subscription 4858103 sync 189974 (PID 9384) exited with exit code 1 2018-08-26 06:32:09.638 IST [13919] LOG: worker process: logical replication worker for subscription 4858103 sync 188985 (PID 9383) exited with exit code 1
This is severe and will eventually break your Publisher side too (the replication slot will grow forever). So, you did something wrong, I hope - don't get me wrong I'd wish the same for myself :) Either you created the subscription while the subscriber already had existing data in the tables, or you are inserting/updating dataI or Ds/keys on the subscriber that cause the problem .
Some 72 lakh times the above errors are occurring. How to prevent this behaviour? Kindly assist me!! Thanks in Advance. Regards, Pavan -- Sent from: http://www.postgresql-archive.org/PostgreSQL-admin-f2076596.html
