Re: Can PostgreSQL create new WAL files instead of reusing old ones?

[Jerry Jelinek <jerry.jelinek@xxxxxxxxxx>]

As Dave described in his original email on this topic, we'd like to avoid recycling WAL files since that can cause performance issues when we have a read-modify-write on a file that has dropped out of the cache.

I have implemented a small change to allow WAL recycling to be disabled. It is visible at:

I'd appreciate getting any feedback on this.

Thanks,
