<listitem>
<para>
Removes the <literal>OID</literal> column from the the table. Removing (setting without)
oids from a table also do not occur immediately. The space an <literal>OID</literal>
uses will be reclaimed when the tuple is updated. Without updating the tuple, both the
space and the value of the <literal>OID</literal> are maintained indefinitely. This is
semantically similar to the <literal>DROP COLUMN</literal> process.
