The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/12/ddl-generated-columns.html Description:
https://www.postgresql.org/docs/12/ddl-generated-columns.html In the below "Consider the differences between a column with a default and a generated column. The column default is evaluated once when the row is first inserted if no other value was provided; a generated column is updated whenever the row changes and cannot be overridden. A column default may not refer to other columns of the table; a generation expression would normally do so. A column default can use volatile functions, for example random() or functions referring to the current time; this is not allowed for generated columns." "a generation expression would normally do so" should be changed to "a generated column" for easier reading
