That's a little strange, but it is documented behavior:

From http://www.postgresql.org/docs/8.4/static/arrays.html :

"However, the current implementation ignores any supplied array size
limits, i.e., the behavior is the same as for arrays of unspecified
length.

The current implementation does not enforce the declared number of
dimensions either. Arrays of a particular element type are all
considered to be of the same type, regardless of size or number of
dimensions. So, declaring the array size or number of dimensions in
CREATE TABLE is simply documentation; it does not affect run-time
behavior."
