### Is your feature request related to a problem or challenge? > Concatenates the two arrays. Concatenating a null or empty array is a no-op; otherwise the arrays must have the same number of dimensions (as illustrated by the first example) or **differ in number of dimensions by one (as illustrated by the second)**. Ref https://www.postgresql.org/docs/current/functions-array.html Concat with the same number of dimensions is already supported, but the dimensions differ by one is not. # Same dimensions concat select array_concat(make_array([1,2], [3,4]), make_array([5, 6])) ---- [[1, 2], [3, 4], [5, 6]] # Diff 1 concat select array_concat(make_array([1,2], [3,4]), make_array(5, 6)) --- [[1, 2], [3, 4], [5, 6]] Their result should be the same ### Describe the solution you'd like We can add an additional dimension to the lower dimension array, then contact them ### Describe alternatives you've considered Anything else that works ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
