Hello, As suggested by you, we upgraded the postgres to version 9.3.14. Also we removed all the patches we had applied before. But the issue is still observed in the latest version as well.
The issue is seen during normal run and only observed in the standby node. This time as well, the same error log is observed. node-1 postgres: [18-1] PANIC: btree_xlog_delete_get_latestRemovedXid: cannot operate with inconsistent data Can you please share your inputs which would help us proceed further?

Well, I looked through the git history from 9.3.9 to 9.3.11 and I don't see anything that seems likely to explain a problem here. If you can reproduce this, which it sounds like you can, maybe you could create a self-contained test case for other people to try? Also worth noting is that the current 9.3.x release is 9.3.14. You might save yourself some time by updating and seeing if it still reproduces in 9.3.14. regards, tom lane -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
