I have a data directory that was created by Postgres 12 (I thought beta 3 but now am not sure anymore) running in Docker.
I have installed Postgres 12b3 as a Systemd service and am trying to set the cluster to the same PGDATA. I have set the owner of the directory to postgres:postrgres, and the permissions to 0700, but I'm getting the following error:
2019-08-22 23:40:48.759 UTC [23044] FATAL: database files are incompatible with server
2019-08-22 23:40:48.759 UTC [23044] DETAIL: The database cluster was initialized with CATALOG_VERSION_NO 201906161, but the server was compiled with CATALOG_VERSION_NO 201907221.
How can I start up the Cluster?
Is version 201906161 beta 2?
Would running PG12 beta 2 work?
Would running initdb destroy the data?
Thank you,
