I think a fully functional ALTER TABLE command may be hard to implement, as it includes changes of columns, types, constraints, etc... We should take a gradual approach here and implement this command by phases.
I would propose that in the first phase we simply add the capability to add and remove columns to a table. This way, given that we already support CREATE INDEX command, the new column can be immediately indexed within the cluster and used for query execution. Does this sound like a plan? D.
