SET QUERY_LIMIT bug report

I see there's still the command:

SET QUERY_LIMIT  (even in the docs)
but it doesn't work.
prova=> select * from test limit 1;num|flt8
----+----
1.00|   1
(1 row)

prova=>
prova=> set query_limit = '1';
SET VARIABLE
prova=> select * from test; num| flt8
-----+-----1.00|    12.34|2.343
-3.00|   -3
(3 rows)

prova=> show query_limit;
NOTICE:  query limit is 1
SHOW VARIABLE
