Hi,

I found a post with some instructions for resizing without locking up
the table, but would like to get some re-assurance that this is the best
way:

How does that affect data storage and future updates on existing rows?

I did not see any feedbacks about this topic.

I need confirmation that it is safe to do this! Personally, I feel that it is specially useful when there are many view dependencies. Update from data dictionary, all views will be updated automatically, right?

Thanks a lot!
