Re: Stored columns: Unexpected varattno in expression to be mapped

as a Postgres user for about half a year, I think I found a bug in psql (PostgreSQL) 12.2 (Debian 12.2-2.pgdg100+1).

Steps to reproduce:

Type the following commands into a PSQL shell:

postgres=# create table mytable (foo text generated always as (bar) stored, bar text);

CREATE TABLE

postgres=# create temporary table mytemp1 (like mytable);

CREATE TABLE

postgres=# create temporary table mytemp2 (like mytable including all);

ERROR:  unexpected varattno 2 in expression to be mapped

I would be happy if this bug could be fixed in a later release (provided that it has not already been).
