Native support is probably "zero" as Simon is implying.
Most BI ends up needing scalar values for calculations and display. Two
dynamics resulting because of this: either you have to supply your own SQL
in the BI tool and perform the needed conversions or you can create a BI
integration layer within your model so the tools can hit pre-defined schema
with the conversions already in place and the SQL the tools generate can be
used as-is.
I get what you are saying but all I am coming up with more questions to ask
regarding your use-case. For better and worse most tool developers want to
be vendor agnostic to the largest degree possible. The good news is there
are a number of open-source projects that may suffice and that with a strong
enough need a PostgreSQL specific module could be developed. Unless you are
willing to try and sponsor some of that work I'd suggest being open with you
needs and desires and give others a chance to buy into and leverage the
ideas and suggestions and thus ideally increase the demand for such.
