1. What is the highest version of PostgreSQL supported with Hubzilla?
2. Do you have the steps to switch from a local database to an external database? In particular, where in Hubzilla config we can specify the database hostname, database port, database name, database user and database password?
3. Will Hubzilla work if we deploy it to a Docker container? If yes, is there a Docker image for this ? If not we can make our own but anything you can share on this will be helpful
4. Hubzilla sizing - Is there an official sizing guide? For example, use X number of CPU cores / Y amount of memory for Z number of concurrent users? Even a reference sizing is helpful
