bug: virtual generated column can be partition key - Mailing list pgsql-hackers

hi.
While trying to make the virtual generated column be part of the partition key,
I found this bug.
it also influences the stored generated column, i added a test
on generated_stored.sql.

CREATE TABLE gtest_part_key (
    f1 date NOT NULL, f2 bigint,
    f3 bigint GENERATED ALWAYS AS (f2 * 2) VIRTUAL)
    PARTITION BY RANGE (f3);

ERROR:  cannot use generated column in partition key
LINE 4:     PARTITION BY RANGE (f3);
                                ^
DETAIL:  Column "f3" is a generated column.

the following is essentially the same as above, it should also fail.

CREATE TABLE gtest_part_key (
    f1 date NOT NULL, f2 bigint,
    f3 bigint GENERATED ALWAYS AS (f2 * 2) VIRTUAL)
    PARTITION BY RANGE ((f3));
