Someone else replied to this with an implementation..

The driver's Array support is pretty bad currently. It will only work if
the Array implementation implements:

 - getBaseTypeName() returns the underlying postgresql type name ("int")
 - toString() returns a correctly-formatted array string ("{1,2,3}")

Proper support for arbitrary Array implementations (and bare arrays via
setObject) has been on my todo list for ages but it's no longer a high
priority for our application so I doubt I'll work on it any time soon :/

JDBC has no mechanism to specify a particular array type via a Types.*
constant unfortunately :(

Using protocol version 2 as Dave Cramer suggests is a short-term fix but
you don't want to be using that in the longer term..
