jdbc high memory consumption for RAISE NOTICE output using function-call in Java - Mailing list pgsql-jdbc

The function creates ~16MB output. The VM needs ~200MB over statement.executeQuery(...).

CREATE OR REPLACE FUNCTION Test_Grosse_Logdatei() returns INTEGER AS
$$
DECLARE
BEGIN
    FOR i IN 1..150000 LOOP
        RAISE notice '123456789 123456789 123456789 123456789 123456789 123456789 123456789 123456789 123456789 123456789 ';
    END LOOP;   
   
    RETURN 0;
END;
$$
language plpgsql;

How can we reduce this?
