I think TRUNCATE is mentioned because column_list has an impact on all
other DML commands like insert, update, delete that gets replicated
except Truncate. So, leaving Truncate as it is seems okay to me.
- The column list can contain stored generated columns as well. If no
- column list is specified, all table columns (except generated columns)
- are replicated through this publication, including any columns added
- later. It has no effect on <literal>TRUNCATE</literal> commands. See
+ The column list may include any non-virtual columns of the table. If the
+ column list is omitted, the publication will replicate all non-generated
+ columns (including any added in the future) by default. Stored generated
+ columns can also be replicated if
<literal>publish_generated_columns</literal>
+ is set to <literal>stored</literal>.
I find the use of non-virtual in the first line and non-generated in
the second line a bit confusing. Can we keep the first line as it is
(The column list can contain stored generated columns as well.)?
