| Hi!
Basically after upgrade to version 11.5 from 10.6 I experience error messages on streaming replica host “FATAL: terminating connection due to conflict with recovery” and “ERROR: canceling statement due to conflict with recovery”. There is no changes for vacuuming on master nor max_standby_streaming_delay for replica. I tried to correlate errors with vacuuming process on master but according to logs there is no link between them. Somehow I have feeling that when query runs longer than value for parameter max_standby_streaming_delay the query will be terminated regardless vacuuming process on master.
Is there any changes on version 11.5 what may cause it?
Is there any good solution without setting max_standby_streaming_delay=-1 or enabling hot_standby_feedback?
BR, Toomas
