The method to transform a JSON array to an integer array in Postgres is to use the json_array_elements
function to unnest the JSON array, and then cast the resulting elements to integers using the ::integer
operator. Here is an example:
SELECT json_array_elements('[1, 2, 3]')::integer[] AS integer_array;
This will return an integer array [1, 2, 3]
