The reason why it isn't accessible is that some implementations of
connection pools (including one I have written), return a wrapper object
around the connection object. This wrapper object just implements the
java.sql.Connection interface defined by the jdbc spec. If the wrapped
connection (an org.postgresql.Connection object in this case) has extra
methods (such as getInsertedOID()) there is no way to access those extra
methods as the wrapper does not contain them.
If you were using the postgres connection object directly you would
simply cast the object to an org.postgresql.Connection and then you
would be able to access the extra methods. But you can't in this case
because you are dealing with a wrapper object (i.e. something like
com.foo.connectionpool.Connection).
