I think REALbasic has it correct and working.  My suggestion is that 
constructors should now be named "Constructor".

The code is quite simple.  Define a subclass QMDatabase of VDatabase.  
Then add the following method.

Sub Constructor(inHost as String, inUserName as String, inUserPassword 
as String, inPort as Integer=15432, inTimeOut as Integer=60, inOptions 
as String="")

   Super.VDatabase(inHost as String, inUserName as String, 
inUserPassword as String, inPort as Integer=15432, inTimeOut as 
Integer=60, inOptions as String="")

   //subclass code to create VTable objects here
End Sub

REALbasic doesn't believe that there is such a method as 
Super.VDatabase with this signature; it only claims to know about the 
other VDatabase constructor.
