On the MERGE page, the description of the privileges required could be taken to imply that the SELECT privilege is required on all columns of the data source, whereas actually it is only required on the columns referred to by conditions or expressions in the MERGE command. Re-word it to make that a little clearer, and mention expressions as well as conditions. Also, add a glossary entry for MERGE, and nearby on the glossary page, mention MERGE in the list of commands that cannot update a materialized view. Noted by Jian He.
