Description: raise doesn't add end of line
Details:

Many RAISE statements in a function no more
adds end of line (CR/LF) on every message, even if it contains chr(10)
explicitely. Just when the function ends, or inserting chr(10) in the middle
of the message a CR/LF is added in the log.

For instance consider the function:

CREATE OR REPLACE FUNCTION r()
RETURNS void AS
$BODY$begin
raise notice 'Break the 1st%line...', chr(10);
raise notice 'eol on 2nd line...%', chr(10);
raise notice '3rd line';
raise notice '4th line';
end; $BODY$
LANGUAGE 'plpgsql' VOLATILE
COST 100;
ALTER FUNCTION r() OWNER TO postgres;

Run it:
SELECT r()

And you get:

Run it:
SELECT r()

And you get:

NOTICE: Break the 1st
line...NOTICE: eol on 2nd line...NOTICE: 3rd line
