ERROR: operator does not exist: jsonb - jsonb
LINE 1: select jsonb('[2,3,1]') - to_jsonb(1);

HINT: No operator matches the given name and argument types. You might need
to add explicit type casts.
broadway=#
Given that the first statement show the array contains an element that
matches to_jsonb(1) the fourth statement should delete the third ( index 2)
item from the array, not return an argument type mismatch. This would solve
the problem of not being able to delete from a JSON integer array by value
