Subject: [PATCH] fix: support dual-stack ipv4 and ipv6 machines

Previously, LISTEN_ADDR was set to hostname -i which might return
multiple ip addresses separated with space, which is not compatible with
cases like ${LISTEN_ADDR}:5432

When listen on all the addresses is needed, we'd better use *:5432
