I don't think so...


create temporary table seq as select * from generate_series(1,20) as g(id);
select * from seq where id in (5,2,12);id
---- 2 512


select * from seq where id = 5 or id = 2 or id = 12;id
---- 2 512

It certainly doesn't work.

You have to order it by something, like:

select * from seq where id in(5,2,12) order by id=5 desc,id=2 desc,id=12 desc;id
---- 5 212
