When <literal>true</>, tables that are referenced by a query will be
automatically added to the <literal>FROM</> clause if not already
present. The default is <literal>true</> for compatibility with
previous releases of <productname>PostgreSQL</>. However, this
behavior is not SQL-standard, and many people dislike it because it
can mask mistakes. Set to <literal>false</> for the SQL-standard
behavior of rejecting references to tables that are not listed in
<literal>FROM</>.
