Hello! Im working with the ltree [1] datatype and have labels that can not used directly in ltree and a want to get a tree like strukture ordered by the labels.
IE, I've got a table CREATE TABLE t ( tree LTREE, label TEXT ); and data like tree label -------------------------- root.1 z root.2 c root.2.1 a root.2.2 b root.3 i root.4 f root.4.1 k root.4.2 c I need a VIEW that ordery by "by tree but by label in the same hirachie", so the output should be root.2 c root.2.1 a root.2.2 b root.4 f root.4.2 c root.4.1 k root.3 i root.1 z Any idea? Thanks, AXEL.
