Hello,
We have recently upgraded our postgres cluster from 9.1 to 9.6. we are having a difficult time creating our slave server. We have encountered the "contrecord is requested" error which is preventing the slave from starting up. We have recreated the slave , still no luck. Our master is running apparently without issue. We did not use the pg_basebackup command but the
pg_start_backup
tar
pg_stop_backup
How can we debug? I am afraid to stop and start our master server in case there is data corruption and it will not start. I have however successfully restored the database using a pg_dump onto another machine (I understand that this cannot be used for slave creation, I just wanted to verify that I could restore the new upgraded db). Would it be better to use the streaming pg_basebackup command?
Please advise.
Eric
