Yes, it might be better, but I don't see how it fails otherwise ?

here the JVM level's LogLevel is set to be DEBUG.

source.getConnection()
   -->DriverManager.getConnection(getUrl(), user, password)
      ->getUrl()
           sb.append("&loglevel=").append(logLevel);

here the Connection's  LogLevel is set to be the initial value 0(*) via URL,
although nobody set DataSource's LogLevel by calling BaseDataSource.setLogLevel().

I think it's better append "loglevel" to URL only when
BaseDataSource.setLogLevel() was called.
so a Connection created by DataSource.getConnection() can inherit JVM level's LogLevel setting
just like which one created by DriverManager.getConnection().


*)0 is the initial value and not a valid LogLevel,
valid values are INFO (1) and DEBUG (2).

    Hi,

    In the following code,log can not be output as expected.

    -------------------------------------
    org.postgresql.Driver.setLogLevel(org.postgresql.Driver.DEBUG);
    DataSource source = (DataSource)new InitialContext().lookup("DataSource");
    Connection con = source.getConnection();
    -------------------------------------

    It's seems to be a problem,
    I have made a small patch to fix it.
    Hopefully this useful.
