On the master or on the slave, or on both? I thought shipping the archived WAL files from the master to the slave did this already?

In your case you need to transfer the WAL files using streaming replication, so you need to set wal_keep_segments to a value high enough on master such as the slave can can up. For reference:

That document mentions “(However, the standby server can recover by fetching the segment from archive, if WAL archiving is in use.)”. That appears to be my problem, that is not actually occurring in my case.
