If I understand your problem correctly, you are trying to use the replica to run queries for some kind of report. For those cases, I recommend setting up a logical replication which will allow you to have a replica that can be modified based on your needs. For instance, on the target database (replica) you could create indices to improve the performance of your query. An analysis of the execution plan would be necessary, of course.

Hi All
Does wal_level = logical can resolve the issue of replication lag?

Hi everyone,
We have a setup of primary and replica database. We are using the replica as read only purpose. But the queries are long running queries that takes 30 minutes to complete.
Do we have any settings in place that will not show replication lag and the queries also executes on replica database without competition on WAL reply?
