I made a new patch to avoid the above problem.


But i found a new another problem.
In the following code,source2.getConnection() fail to output log as expected.
----------------------------------------
PGPoolingDataSourcesource = new PGPoolingDataSource();
source.setLogLevel(2);
Connection con = source.getConnection();//OK, log does output

Properties props = new Properties();
props.put(InitialContext.INITIAL_CONTEXT_FACTORY,  "org.postgresql.test.util.MiniJndiContextFactory");
InitialContext initialContext = new InitialContext(props);
initialContext.rebind("DataSource", source);

BaseDataSource source2 = (BaseDataSource) initialContext.lookup("DataSource");
con = source2.getConnection();//NG, log does not output
----------------------------------------

The reason is that loadBaseDataSource(BaseDataSource ds, Reference ref)
fail to copy all properties from ref when source2 was created.
So the loglevel of source2 remains to be the defualt value 0.
Not only loglevel, some other properties such as "ssl" have the same problem.
