No the question about extension means that given a PGResultSetMetaData 
object you cannot call the standard ResultSetMetaData methods.  This is 
solely a convenience issue.  If you wanted to call both getColumnName and 
getBaseColumnName you'd need to maintain two references (one to the
ResultSetMetaData object and another to the PGResultSetMetaData object).  
If PGResultSetMetaData extended ResultSetMetaData you'd only need a 
reference to the pg version.  We have a separate pg specific method 
because we believe that function is useful, but does not match the spec 
for getTableName.  Have you read the entire thread?
