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 -established. +Each walsender allocates an entry from the WalSndCtl array, and tracks +information about replication progress. User can monitor them via +statistics views.
