i don't know what pg_attribute is, but sound to me like it is a good
sollution.

it wouldn't matter much to me, if "select *" wouldn't be expanded in the
correct order, but it might worry other users.
the first thing to achieve is to define and offer a place where tools
can store the ordering information.
the second would be to make "select *" to use this information, although
this information should be well cached than if "select *" is expected
to be used often.
