The <code class="literal">SET</code> clause will replace the list of tables/schemas in the publication with the specified list; the existing tables/schemas that were present in the publication will be removed. The <code class="literal">ADD</code> and <code class="literal">DROP</code> clauses will add and remove one or more tables/schemas from the publication. Note that adding tables/schemas to a publication that is already subscribed to will require an <code class="literal">ALTER SUBSCRIPTION ... REFRESH PUBLICATION</code> action on the subscribing side in order to become effective. Note also that <code class="literal">DROP TABLES IN SCHEMA</code> will not drop any schema tables that were specified using <a class="link" href="sql-createpublication.html#SQL-CREATEPUBLICATION-FOR-TABLE"><code class="literal">FOR TABLE</code></a>/ <code class="literal">ADD TABLE</code>, and the combination of <code class="literal">DROP</code> with a <code class="literal">WHERE</code> clause is not allowed. </p><p> The fourth variant of this command listed in the synopsis can change all of the publication properties specified in <a class="xref" href="sql-createpublication.html" title="CREATE PUBLICATION"><span class="refentrytitle">CREATE PUBLICATION</span></a>. Properties not mentioned in the command retain their previous settings. </p><p> The remaining variants change the owner and the name of the publication. </p><p> You must own the publication to use <code class="command">ALTER PUBLICATION</code>. Adding a table to a publication additionally requires owning that table. The <code class="literal">ADD TABLES IN SCHEMA</code> and <code class="literal">SET TABLES IN SCHEMA</code> to a publication requires the invoking user to be a superuser. To alter the owner, you must be able to <code class="literal">SET ROLE</code> to the new owning role, and that role must have <code class="literal">CREATE</code> privilege on the database. Also, the new owner of a <a class="link" href="sql-createpublication.html#SQL-CREATEPUBLICATION-FOR-ALL-TABLES"><code class="literal">FOR ALL TABLES</code></a> or <a class="link" href="sql-createpublication.html#SQL-CREATEPUBLICATION-FOR-TABLES-IN-SCHEMA"><code class="literal">FOR TABLES IN SCHEMA</code></a> publication must be a superuser. However, a superuser can change the ownership of a publication regardless of these restrictions. </p><p> Adding/Setting any schema when the publication also publishes a table with a column list, and vice versa is not supported. </p></div><div class="refsect1" id="id-1.9.3.25.6"><h2>Parameters</h2><div class="variablelist"><dl class="variablelist"><dt><span class="term"><em class="replaceable"><code>name</code></em></span></dt><dd><p> The name of an existing publication whose definition is to be altered. </p></dd><dt><span class="term"><em class="replaceable"><code>table_name</code></em></span></dt><dd><p> Name of an existing table.
