hi, All,
I intend to do a basebackup on a hot standby node. I followed the instructions on http://www.postgresql.org/docs/9.2/static/app-pgbasebackup.html to turn full_page_writes on at master and other settings on standby.
When I try to select pg_start_backup('backuplabel'); on the standby instance, it give me the following:
ERROR: recovery is in progress
HINT: WAL control functions cannot be executed during recovery.
I tried select pg_xlog_replay_pause(); before the select pg_start_backup('backuplabel'); but that does not help.
Also why select pg_is_in_recovery(); always returns true when select pg_is_xlog_replay_paused(); is true? I thought when I do select pg_xlog_replay_pause(); the standby should not be in recovery
Please help if you know anything about this. Thank you.
best,
Ying
