Is there a built-in way to look for NULL array elements? I was
thinking of something like NULL IS DISTINCT FROM ALL (array expression)
but that doesn't work:
test=> SELECT NULL IS DISTINCT FROM ALL (ARRAY[1, 2, 3]);
ERROR: syntax error at or near "ALL" at character 30
LINE 1: SELECT NULL IS DISTINCT FROM ALL (ARRAY[1, 2, 3]); ^
