Looks like it could be useful to make the database 'log' the DDL
statements and having the ability to export those to a script starting
from a certain version.
It would probably still need user intervention, as sometimes experiments
and mistakes require fixing things - which would result in bogus or
non-optimal DDL statements in the log.
There's also sometimes the need to update data between statements, for
example when adding a new NOT NULL column to a table. Not sure what to
do in that case. Automating that would require some server side
'intelligence'...
