Because code using them would be broken anyway by other changes in 8.1 --- for example, using pg_keypositions to iterate over function arguments would now be wrong because there isn't a fixed upper limit on number of arguments. If you were using them, you'll need to tell us what for in order to get advice about what to do instead. regards, tom lane
