SELECT * FROM pg_stat_activity WHERE state = 'active';
So you can identify the PID of the hanging query you want to terminate, run this:
SELECT pg_cancel_backend(PID);
"Nesting performs a join across two buckets. But instead of producing a cross-product of the left and right hand inputs, a single result is produced for each left hand input, while the corresponding right hand inputs are collected into an array and nested as a single array-valued field in the result object."
