Hi everyone,

We just moved to PG9.6 from 9.1 (yeah, not my choice to wait this long). In 9.1 I had to make the archive location (NFS in my case) available to all the mirrors running PG so that they could catch up whenever they fell behind. I thought I read somewhere that in 9.6, as long as the WAL log is available on disk or in the archive the replication server will provide that to the replication client, and my archive NFS mount didn't have to be available to all replication clients. It doesn't seem to be operating that way though. Did I completely remember that wrong or did I misunderstand something?
