well. in postgresql rows do change position. and even in mssql depending
on position from table files is a very big mistake.
suggestion - add default "order by" by some id or timestamp column, and
modify it to fit your user preferences.
for example:
let's say that you have rows with ids: 1,2,3
by default you get them in order: 1,2,3.
if user wants to change the ordering to 2,3,1, store his preferences in
some other table and do it like this:
select t.* from table t join preferences p on t.id = p.id_in_table where
p.user = 'current user' order by p.ordering;
