Upgrade version of a cluster

[Overcrash86]

Hi,

Is there a possibility to upgrade a cluster from older to newer version ?
if i just try modify the version and set "postgresql_exists='true'" i got an error due to postgresql_data_dir not initialized :

ex from v12 cluster to v13 :

TASK [patroni : Prepare PostgreSQL | make sure the postgresql log directory "/var/log/postgresql" exists] ***************************************************

Hi @Overcrash86

Please note that the original design goal of this playbook was more concerned with the initial deployment of a PostgreSQL HA Cluster and so it does not currently concern itself with performing ongoing maintenance of a cluster.

Currently, it is not implemented. Minor updates and Major upgrades are planned (TODO).
