Table versions

[Trausti Thor Johannsson]

How do I add fields to a table and can I set a specific version on  
tables ?

What I mean, I say that a table is version 1.0 with one field

name as vstring

then I quickly notice that I need more information, so I would like to  
add

height as vinteger

and I call it version 1.1 or 2.0 (not a big deal)

then for version 3.0 I add

weight as vfloat
haircolor as vstring
...


But I would like my tables to work with any version of my software, so  
how do I do this directly in the database, or do I just program it  
with code ?
