Hello all,
I hope someone will can help me.
Then, where's the difference between the result of (select array_agg(end_id::integer)::integer[] as id from n2) AND '{28411,25582}'
There isn't...though technically the former is an integer array and the later is an unknown literal. It gets implicitly cast, I think, to an int[] so that it can get matched to the only? function with that name.
A self-contained example would likely help...those who are responsible for pgrouting. The error is coming from the function so debugging it from the inside would help.
Does the order of the integers matter?
