Research direction

Reproduce the report with HugeGraph 1.5.0 by starting the server with bin/start-hugegraph.sh and inspecting PostgreSQL connections, then stop it with bin/stop-hugegraph.sh for comparison. No source file or test is named; done means identifying why the connections remain open during operation and verifying that the expected connections are released without stopping HugeGraph.
