[Django]-How can I fix PostgreSQL canceling statement error on Google SQL?

If “Google SQL” allows that, you can set max_standby_streaming_delay to -1 so that replication is delayed if a conflict is detected.

Then the query will not be canceled, but replication may lag if applying changes would cause a conflict.

Consider getting an “unfettered” PostgreSQL.

If you would like set hot_standby_feedback = on, I’ll suggest that you indicate your interest in the open feature request on Google Cloud Platform’s Public Issue Tracker tool. That way someone can look into the handling query conflict issues your Cloud SQL PostgreSQL instance encountered.

I’ve also been monitoring an open thread in the Issue Tracker about making max_standby_archive_delay and max_standby_streaming_delay flags available to users to set. You can track it there as well. Hope this helps!
