So, the problem can be massive, because it needs to add the port parameter (or an configurable connection url), and there is a lot of place where the code is making the assumption this is not happening.
So we need:
- to add the config param for external DB parameters,
- modify packaging and DB configuration scripts/policies
- see wherever it breaks.

Targeting 9.0 as a middle ground, but:
- if it happens to be hyper simple, we will backport it to 8.3,
- if it is discovered to be complicated and breaks things, perhaps we will even need to make it 9.1 for reliability.
