So my friend…
Personally, for production environments… I wouldn’t trust anything that wasn’t in Camunda’s official documentation.
I just found an old post here on the forum, in which a Camunda contributor informs that Camunda’s Roadmap did not support Postgres 12 for Camunda 7.12… in your case you need an even more current version than this one (Postgres 13).
But that doesn’t mean it won’t work…
So it’s like I said above… I wouldn’t… but it’s at your own risk.
