Three answers for the price of one ;-) :
1. Why are you trying to constrain the order in an INSERT in the first
place? Tuple order in a table is meaningless under SQL semantics.
2. If you really feel you have to have that, you could rely on the
sorting done implicitly by DISTINCT:
INSERT INTO pledge_classes (year, semester)SELECT distinct pyear, pseason from load_brosWHERE pyear is not nullAND
pseasonis not null;
3. 7.1 will allow you to use an ORDER BY here, pointless though it is.
