<div dir="ltr">I was just looking at Many to one version, the example reads<div><pre style="overflow-x:auto;overflow-y:hidden;border-color:rgb(12,55,98);border-style:dotted;border-width:thin;margin-top:0px;margin-bottom:12px;padding:0.8em;background-color:rgb(240,240,240);color:rgb(51,51,51)">SELECT * FROM pgr_maxFlowPushRelabel(

WHERE edge_table.reverse_category_id = c2.category_id
ORDER BY id'
, ARRAY[6, 8, 12], 11
);</pre><div>ie get the max flow from nodes 6 8 and 12 to 11</div></div><div>The listed result sets says </div><div><pre style="overflow-x:auto;overflow-y:hidden;border-color:rgb(12,55,98);border-style:dotted;border-width:thin;margin-top:0px;margin-bottom:12px;padding:0.8em;background-color:rgb(240,240,240);color:rgb(51,51,51)"> seq | edge_id | source | target | flow | residual_capacity

if I remove the ORDER BY id clause I get
seq | edge_id | source | target | flow | residual_capacity

1 | 10 | 5 | 10 | 100 | 30
2 | 11 | 6 | 11 | 130 | 0
3 | 8 | 6 | 5 | 50 | 80

5 | 12 | 10 | 11 | 100 | 0
6 | 13 | 12 | 11 | 50 | 0
ie the result for node 8 is included, is the order by a requirment? is this a bug ?</font></pre><pre style="overflow-x:auto;overflow-y:hidden;border-color:rgb(12,55,98);border-style:dotted;border-width:thin;margin-top:0px;margin-bottom:12px;padding:0.8em;background-color:rgb(240,240,240)"><font color="#333333">regards
