database files are incompatible with server

["Igal @ Lucee.org" <igal@xxxxxxxxx>]

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,
