+ The <literal>LIKE</literal> clause specifies a table from which
+ the new table automatically inherits all column names, their datatypes, and
+ <literal>NOT NULL</literal> constraints.
+ </para>
+ <para>
+ Unlike <literal>INHERITS</literal>, the new table and inherited table
+ are complete decoupled after creation has been completed. Data inserted
+ into the new table will not be reflected into the parent table.
+ </para>
+ <para>
+ Default expressions for the inherited column definitions will only be included if
+ <literal>INCLUDING DEFAULTS</literal> is specified. The default is to exclude
+ default expressions.
