VP can't connect to PostgreSQL database

I have a postgresql db running in docker. Tried to connect to it with the Tools->DB->Database Configureation and a strange ;instance= is appeared in the database name. Database postgres is existing but postgres;instance= of course is not.

If I create the postgres;instance= in the postgres it can connect to it but this is not the expected behaviour.

Test adapter connection failed!
