Hi all, I'm wondering why in COPY TO (file or program) I cannot use generated columns: since I'm pushing data out of the table, why they are not allowed? Example: testdb=# CREATE TABLE test( pk int generated always as identity primary key , ts timestamp default current_timestamp , month int generated always as ( extract( month from ts ) ) stored ); testdb=# insert into test( ts ) values( current_timestamp ); testdb=# copy test to program 'head'; -- ok but silently removes the column COPY 1 testdb=# copy test( month ) to program 'head'; ERROR: column "month" is a generated column DETAIL: Generated columns cannot be used in COPY. Thanks, Luca
