Sure I want a consistent database. Why doesn't?
But log shipping requires you to rsync/var/lib/pgsql/data to the remote server, and that's consistent, so why wouldn't rsync to a local directory also be consistent?

If you want a consistent database (you *REALLY* do), pg_dump is the correct tool.

Subject: [GENERAL] Using cp to back up a database?
Hi,
v8.4.20
This is what the current backup script uses:/usr/bin/psql -U postgres -c "SELECT pg_start_backup('Incrementalbackup',true);"
cp -r /var/lib/pgsql/data/* $dumpdir/data/
/usr/bin/psql -U postgres template1 -c "SELECT pg_stop_backup();"
Should it use rsync or pg_dump instead?
Thanks
