Hi!

I have a postgresql 7.4.2. When i try to use pg_dump i
get the next error:

pg_dump: saving encoding
pg_dump: saving database definition
pg_dump: SQL command failed
pg_dump: Error message from server: ERROR: relation "pg_user" does not exist
pg_dump: The command was: SELECT (SELECT usename FROM pg_user WHERE usesysid = datdba) as dba, pg_encoding_to_char(encoding) as encoding, datpath FROM pg_database WHERE datname = 'db'


How can i take the backup.
protected methods are possible inside abstract class

//class AbstractTest
public abstract class AbstractTest {
private void test() {
System.out.println("Inside test private");
}
protected void test1() {
System.out.println("Inside test protected");
}
void test2() {
System.out.println("Inside test default");
}
public void test3() {
System.out.println("Inside test public");
}
}

//class AbstractImpl

public class AbstractImpl extends AbstractTest {
public static void main(String[] args) {
AbstractImpl ob = new AbstractImpl();
// ob.test();//not possible to instansiate abstract classes
ob.test1();
ob.test2();
ob.test3();
}
}
