Does changing attribute order breaks something?

Hi!

Are there any known issues when changing the attnums?

like :

airport=# update pg_attribute set attnum = 3 where attname = 'abc' and
attrelid = 18328;
UPDATE 1
airport=# update pg_attribute set attnum = 2 where attname = 'foo' and
attrelid = 18328;
UPDATE 1

Does something break or are there any other ideas to change the order of
columns?

regard
