My opinion is that we should keep BC either by building two different
jdbc versions or checking PG version every time getArray() is used (if <
8.2 then primitive types are used, if >= 8.2 then objects). Second
option is quite good, although it doesn't guaranty full BC - let assume
that someone is using jdbc application that was written for pg 8.0, but
after update to 8.2 the code with following statement:
<code>(boolean[]) getArray()</code>
would cause cast exception (Cannot cast from Boolean[] to boolean[]).
