This parameter controls whether a relation referenced in a query but
missing from the FROM clause should be automatically added to
the FROM clause. If enabled (the default), the notice
<literal>Adding missing FROM-clause entry for table "tablename"</literal>
is generated if a relation is automatically added. If not enabled,
an error is raised when an additional extra relation is required.
For SQL standards compliance, this value should be set to
<literal>false</>.
