Linux General and SQL DB provider support status

Hi guys, I would like to know how is the status for linux environment for real production.
I saw that version 4.2 already supports linux, can it be run with other SQL provider rather than MS SQL?
If not, what are the roadmap or ETA for another SQL DB providers (Postgre , MYSQL) ?

We have the same questions. We'd love to run in linux docker containers containing a MySQL compatible DB.

Another dbs support was postponed to the future versions. You can follow that issue and that thread.

We have it running in a Linux Docker container in AWS ECS targeting MS SQL. Would love MySQL support as soon as possible.
