A searched update statement depends on the table being updated, all of its conglomerates (units of storage such as heaps or indexes), all of its constraints, and any other table named in the WHERE clause or SET expressions.

If no columns were specified or the select statement did not include a FOR UPDATE clause, all columns may be updated.Dropping an alias invalidates a prepared update statement if the latter statement uses the alias.Dropping or adding triggers on the target table of the update invalidates the update statement.Specifying DEFAULT for the update value sets the value of the column to the default defined for that table.The DEFAULT literal is the only value which you can directly assign to a generated column.
