Hi Everyone, I would like to ask for your help finding a temporary solution for my problem. I upgraded postgres from 8.3 to 9.0.3 and I have an issue with the order of the returned rows. The following script is a simplification of my real case: create table tmp_1 (field1 integer, field2 integer); insert into tmp_1 values (1, 3); insert into tmp_1 values (1, 3); insert into tmp_1 values (1, 3); insert into tmp_1 values (1, 3); insert into tmp_1 values (1, 3); insert into tmp_1 values (1, 4); insert into tmp_1 values (1, 4); insert into tmp_1 values (1, 4); insert into tmp_1 values (1, 4); insert into tmp_1 values (1, 4); insert into tmp_1 values (1, 4); insert into tmp_1 values (1, 1029); insert into tmp_1 values (1, 1101); insert into tmp_1 values (13, 3); insert into tmp_1 values (13, 3); insert into tmp_1 values (13, 3); insert into tmp_1 values (13, 3); insert into tmp_1 values (13, 3); insert into tmp_1 values (13, 3); insert into tmp_1 values (13, 4); insert into tmp_1 values (13, 4); insert into tmp_1 values (13, 4); insert into tmp_1 values (13, 4); insert into tmp_1 values (13, 4); insert into tmp_1 values (13, 4); insert into tmp_1 values (13, 4); insert into tmp_1 values (13, 1029); insert into tmp_1 values (13, 1101); analyze tmp_1; SELECT distinct field2 FROM tmp_1 WHERE field1 = 13; The result in postgres 8.3 is as follows: 3 4 1029 1101 And it stays the same no matter what the physical order of the records is in the table. I can do random update and I get the same results. It looks like the result is ordered by the distinct fields... The result in postgres 9.0 is as follows: 3 4 1101 1029 not ordered by the distinct fields nor physical order... I am wondering if there is a temporary solution (updates, indexes, ...) to order the result by field1 without changing the statement...
