Does it mean that if I will change any object (view or function) I must
drop all dependent objects ?
example : I want change (number of columns) view viewa
If viewb depend of viewa, I must drop and create viewa and viewb ?
Does it possible that viewb stay temporary (or always) invalid ?recreate viewa will make viewb valid or pgsql return
errorfor viewb ?
