When index recurses to a partition, map columns numbers

Two out of three code paths were mapping column numbers correctly if a
partition had different column numbers than parent table, but the most
commonly used one (recursing in CREATE INDEX to a new index on a
partition) failed to map attribute numbers in expressions. Oddly
enough, attnums in WHERE clauses are already handled correctly
everywhere.
