Using GVM-11/gvmd-9 with PostgreSQL 11 should work. I’ve used that for a longer period on my personal development computer. But it isn’t tested and there is no guarantee because our corresponding products (GOS 5 and 6) are based on Debian Stretch and therefore PostgreSQL 9.6. We are developing and testing for our products of course. If the community is facing issues with other systems varying from our reference system we sometimes can’t give any promises for fixes.
