One way that might work in the current driver is to use PGobject, which
lets you specify the underlying typename to use:
stmt = conn.preparedStatement("SELECT myfunction(?)");
org.postgresql.util.PGobject obj = new PGobject();
obj.setValue("'{1,2,3}'");
obj.setType("int[]");
stmt.setObject(1, obj);
Untested, but in theory this should work even with
setUseServerPrepare(true) in effect.
Also, if you search the archives, quite some time ago (a year?) I posted
a patch that implemented setArray() better, so that you could pass your
own Array implementation to it and have things work correctly. It's out
of date, but might give you a starting point.
