Allow column type to change without worrying about view dependencies - Mailing list pgsql-sql

Good morning,

When there are lots of views and complicated dependencies, it is not 
easy to alter column from varchar(a) to varchar(b).

Is it possible when defining a view, adding cascade or some other key 
word(s) to allow column type change?

When column1 is changed, all related views' column type is changed as well.

Thanks,
