Hi,
The documentation seems to overlook the rewrite condition
when executing ALTER TABLE ADD COLUMN.
The current document states that a volatile DEFAULT will
trigger a rewrite of the table and its indexes. However, the
table and its indexes will also be rewritten when an IDENTITY
column is added, or when a column with a domain data type that
has constraints is added.
What do you think?
Regards,
