On the page regarding compatibility (here)
It is mentioned that:- The ordering of different Agtype, when using <, <=, >, >= from smallest value to largest value is:
1 Edge
2 Path
3 Map
4 Vertex
5 Edge
6 Array
7 String
8 Bool
9 Numeric, Integer, Float
10 NULL
Why is there Edge twice on number 1 and number 5? Which one is correct?
