Bug in org.postgresql.jdbc2.AbstractJdbc2Array

Hi,
I found a bug in the org.postgresql.jdbc2.AbstractJdbc2Array class that 
causes the following exception when an array contains a null value:

Caused by: org.postgresql.util.PSQLException: Bad value for type date : NULL
    at 
org.postgresql.jdbc2.TimestampUtils.loadCalendar(TimestampUtils.java:246)
    at org.postgresql.jdbc2.TimestampUtils.toDate(TimestampUtils.java:402)
    at 
org.postgresql.jdbc2.AbstractJdbc2Array.getArrayImpl(AbstractJdbc2Array.java:210)

I attached a patch that fixes the problem. If you are happy with it, 
please merge it with the HEAD stream.


Thanks


Alessandro
