Hi all! > - checkpoint_segments 1000 > - checkpoint_completion_target 0.9 > - wal_buffers 256MB > - shared_buffers 31 gb > - max_connections 500 I see that some of you are using wal_buffers = 256MB. I was under the impression that Postgres will not benefit from higher value than the segment size, i.e. 16MB. More than that will not do/help anything. What's the reasoning behind setting it to higher than 16MB? Do I have old information?
