Support different database systems

[vs-gtadeu]

Hello!

We've come across this solution today and got really interested in using it. However, we are curious if it would be possible to allow using other database solutions instead of MySQL. For our case, we would be looking into using PostgreSQL.
Looks like the solution is using Knex.js, which seems to support other databases. However, I'm not that familiar with Knex.js to say how complex it would be to do that.

We are also interested in using a different message broker solution than Kafka, but that might be a topic for a different issue.

Apologies if this is a duplicate question/request. I've tried searching for similar questions but couldn't find anything.

hey @vs-gtadeu, this was raised in #144 as well. If this gains traction from the community, I'm not against it, just needs sufficient support by the developers and/or automated testing.

I do use Postgre, but not with schema-registry :)
