Ah, yeah, true. I do use pg_receivexlog --compress for that locally and do a bulk copy of only the compressed WALs needed, when needed... So there is a guarantee that completed segments are durable locally, which is very useful. You should definitely avoid putting that in PGDATA though, the same counts for tablespaces within PGDATA for example. -- Michael -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
