lft and rgt (and additionally root_id & parent_id) are columns used by the Awesome Nested Set plugin, vendored with Redmine (source:/trunk/lib/plugins/awesome_nested_set). Their values are used to determine the position of either a project or an issue in a nested tree hierarchy.

See I have upgraded to 1.0.1 ,significance of lft and rgt for some more info and references to documentation which explains the way tree traversal is executed on projects and issues (modified preorder tree traversal).
