Multiple KONG_PG_DATABASE names in a single kong container definition

Use case - I am deploying separate kong proxy container for each backend with different schema (KONG_PG_DATABASE), so that I would be able to use single RDS.

Since, if KONG_PG_DATABASE is different, then kong admin container also will be spawned separately for each backend service.

Query: Is it possible to make single kong admin container with multiple KONG_PG_DATABASE ? If it possible, then I would have Centeralize Kong Admin.
