…ibpq psycopg2-binary bundles its own libpq 9.6, which does not support the target_session_attrs connection parameter (requires libpq >= 10). This causes Patroni replicas to log errors every second: psycopg2.ProgrammingError: invalid dsn: invalid connection option "target_session_attrs" The error originates in Patroni's rewind.py check_leader_is_not_in_recovery(), which sets target_session_attrs='read-write' for PG >= 10. Switching to psycopg2 (non-binary) compiles from source against the system's libpq-dev, which fully supports the parameter. libpq-dev is already present via the postgresql-server-dev dependency.
