I have tried couple of way to upgrade but they are not production friendly: I have tried pg_upgrade but as it require to stop the server we can't do it. I have tried with --link option too but it also take time. I have created replication and I tried to take pg_basebackup using 11.3 version but the backup was created with 9.4 version. I have also tried to do the same with pglogical but it is showing pglogical schema not found. please tell me the proper way to upgrade our 2TB of production database. -- Thanks & Regards Rahul Chordiya Tech-Geek && DevOps && Full Stack Developer Mobile: +91 998 153 4313<tel:919981534313> [🌳] Please do not print this email unless absolutely necessary.
