Ah - they're are two types of generated columns > There are two kinds of generated columns: stored and virtual. A stored generated column is computed when it is written (inserted or updated) and occupies storage as if it were a normal column. A virtual generated column occupies no storage and is computed when it is read. Thus, a virtual generated column is similar to a view and a stored generated column is similar to a materialized view (except that it is always updated automatically). https://www.postgresql.org/docs/12/ddl-generated-columns.html https://www.postgresql.org/docs/12/ddl-generated-columns.htm...
