Oh, they're created all right. But they're created according to what the name ought to be now given the new column name, and the setval() commands in the old dump are wrong for that. Per Doug's response, use the 8.1 pg_dump if you can, as it knows how to generate setval() calls that can deal with this effect. There's no very good solution for it in 7.4 unfortunately --- if you want to use the old pg_dump, you have to do the setvals by hand after loading the dump. Note that you'd have the same problem trying to reload that dump into 7.4 ... regards, tom lane
