Hello! When I try to fill an array with the concatenation operator, like UPDATE test SET myint = myint || ARRAY[123] WHERE id = 1 that before that statement was null, then it is also null after that statement. But if there is already something in that array and I execute that statement, then everything works fine and one can find the 123 there, too. Is this the normal behavior? Is there a way to "concatenate" to null arrays as well, or do I have to test this inside my script, and if it is null fill it normal for the first time? Best regards, Kai
