Are you saying it's an unordered list for which the order matters? That seems a bit peculiar.
What would probably work is to split the array around the value to remove, and merge those arrays again.
Something like this:
=> select (ARRAY[100, 101, 102, 103, 104])[1:2] || (ARRAY[100, 101, 102, 103, 104])[4:5];
?column?
-------------------
{100,101,103,104}
(1 row)
