'current' timestamp chokes jdbc driver

If you set a timestamp field to be 'current' as per
http://www.ca.postgresql.org/docs/postgres/datatype-datetime.html#AEN322
jdbc chokes on selecting that value:
Bad Timestamp Format at 0 in current
        at
org.postgresql.jdbc2.ResultSet.getTimestamp(ResultSet.java:517)
        at org.postgresql.jdbc2.ResultSet.getObject(ResultSet.java:825)

So I created this patch.  I'm not sure if this is correct though,
because maybe its the servers job to convert these.
