Re: Queries in replica are failing

[ROHIT SACHDEVA <sachdeva.rohit648@xxxxxxxxx>]

I received this error when i set  max_standby_streaming_delay to -1 and  max_standby_archive_delay to 30 seconds.

The following processes were terminated on your read replica because they were interfering with the replay of transaction logs: [18218].

I was also receiving an error when i set hot_standby_feedback.

Kindly suggest.

The only safe way to avoid this error is to set "max_standby_streaming_delay" to -1.
