Hi All,

I posted about this last year [1] -- sharing our experience
hitting WAL archival gaps in production and asking for last_archived_wal
to be surfaced on the standby via keep-alive messages.

Glad to see Andrey's  patch reviving this.

If the full shared mode lands, great. But even if that's too much for
now, just exposing last_archived_wal on the standby -- in
pg_stat_wal_receiver or anywhere queryable -- would unblock everyone
solving this problem externally.

Thanks,
Harinath
