Hrm. What about this hunk?
-Each walsender allocates an entry from the WalSndCtl array, and advertises
-there how far it has streamed WAL already. This is used at checkpoints, to
-avoid recycling WAL that hasn't been streamed to a slave yet. However,
-that doesn't stop such WAL from being recycled when the connection is not
