Thread: Reg: Size difference
Hi Team
I have been using PostgreSQL for the past 6 years. PostgreSQL has significantly impacted my life, providing me with great opportunities for knowledge and self-development.
I'm currently facing a strange issue with PostgreSQL 15.0. I have a primary-standby setup that is in sync, with a replication slot in place. There are 18 databases, and one of the databases on the primary side is 104 GB, while the same database on the standby side is 216 GB. Both are in sync with zero delay.
Could this be a bug? If so, has it been resolved in newer releases? If it is not a bug, how can this issue be fixed? Is there a solution or any supporting documentation available?
Thanks & Regards,
Vinay Kumar
Hi, > Could this be a bug? If so, has it been resolved in newer releases? If it is not a bug, how can this issue be fixed? Isthere a solution or any supporting documentation available? Hard to tell based on the provided information. Do you know which files differ in particular? It could be as simple as a huge text log file that was never rotated. Also I'm a bit surprised that you use 15.0. I know several people who believe that using the next major version of Postgres before the .2 minor release is not the best idea, and I can understand this point of view. Postgres 15 had 8 updates in the past several years [1] with multiple improvements / bug fixes in every one of them. You should probably consider installing these updates.

Hi,
WAL and log files are being rotated properly. The issue is with a database named services_mfs. On the primary cluster, the services_mfs database is 104GB, but on the standby cluster, it is 216GB, even though both cluster are in sync. The standby database is only used in case of a crash, which is managed by a Patroni cluster with etcd.
Thanks,
