+        This parameter specifies the default compression method to use
+        when compressing data in <acronym>TOAST</acronym> tables.
+        It applies only to variable-width data types.
+        It may be overriden by compression clauses in the
+        <command>CREATE</command> command, or changed after the relation is
+        created by <command>ALTER TABLE ... SET COMPRESSION</command>.
+
+        The supported compression methods are <literal>pglz</literal> and
+        (if configured at the time <productname>PostgreSQL</productname> was
+        built) <literal>lz4</literal>.
+        The default is <literal>pglz</literal>.
