I want to create a database backup when PG is running, so I call
pg_start_backup(''), scp the data to a backup directory, pg_stop_backup.
Then I reboot PG , PG boot failed with log like "unexpected pageaddr X/X in log
file X, segment X, offset X" "WAL ends before end time of backup dump".
Then I check the failure XLOG file, found the error page contains a pageaddr
8K before it should be, and the failure XLOG record a ONLINE CHECKPONT with 60
bytes in former page, the other 4 bytes missing.
Any one met this before? Please help me!
