invalid memory alloc request size 0 - Mailing list pgsql-hackers

Hi all,
strange errors with a empty table:

kalman=# create table test();
CREATE TABLE
kalman=# select * from test t union select * from test t1;
ERROR:  invalid memory alloc request size 0


I think this have to return:


--
(0 rows)
