Hi. I've experienced very similar behavior and log message. I do not know what is the problem in detail but my guess is that standby system has data which is incompatible to accept streaming replication of the master.
The way I solved is the following on Ubuntu11.04. Suppose postgresql.conf and recover.conf (on standby) are ready. 0. Stop postgresql on standby standby# /etc/init.d/postgresql stop 1. invoke pg_start_backup() on master master# sudo -u postgres psql -c "SELECT pg_start_backup('2011-08-15_04:49)" 2. remove data files on standby standby# cd /var/lib/postgresql/9.0/main standby# /bin/rm -rf base pg_* standby# mkdir pg_xlog; chown postgres.postgres pg_xlog; chmod 700 pg_xlog 3. copy data files master# rsync -av --delete /var/lib/postgresql/9.0/main --exclude=pg_xlog --exclude=postmaster.pid --exclude=server.crt --exclude=server.key /path/to/standby/data/directory 4. invoke pg_stop_backup() on master master# sudo -u postgres psql -c "SELECT pg_stop_backup()" 5. start postgresql on standby standby# /etc/init.d/postgresql start Then, I found streaming replication just started to work. -- View this message in context: http://postgresql.1045698.n5.nabble.com/streaming-replication-one-problem-several-questions-tp4687602p4698911.html Sent from the PostgreSQL - general mailing list archive at Nabble.com. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
