Replace custom parsing of order by and segment by lists with the postgres parser. The segment by list is now parsed in the same way as the GROUP BY clause and the order by list in the same way as the ORDER BY clause. Also fix default for nulls first/last to follow the PG convention: LAST for ASC, FIRST for DESC.
