</pre></div><div class="refsect1" id="id-1.9.3.25.5"><h2>Description</h2><p>
The command <code class="command">ALTER PUBLICATION</code> can change the attributes
of a publication.
</p><p>
The first three variants change which tables/schemas are part of the
publication. 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. If <code class="literal">ONLY</code> is specified before the
table name, only that table is affected. If <code class="literal">ONLY</code> is not
specified, the table and all its descendant tables (if any) are
affected. Optionally, <code class="literal">*</code> can be specified after the table
name to explicitly indicate that descendant tables are included.
</p><p>
Optionally, a column list can be specified. See <a class="xref" href="sql-createpublication.html" title="CREATE PUBLICATION"><span class="refentrytitle">CREATE PUBLICATION</span></a> for details. Note that a subscription
having several publications in which the same table has been published
with different column lists is not supported. See
<a class="xref" href="logical-replication-col-lists.html#LOGICAL-REPLICATION-COL-LIST-COMBINING" title="Warning: Combining Column Lists from Multiple Publications">Warning: Combining Column Lists from Multiple Publications</a> for details of
potential problems when altering column lists.
</p><p>
If the optional <code class="literal">WHERE</code> clause is specified, rows for
which the <em class="replaceable"><code>expression</code></em>
evaluates to false or null will not be published. Note that parentheses
are required around the expression. The
<em class="replaceable"><code>expression</code></em> is evaluated with
the role used for the replication connection.
</p></dd><dt><span class="term"><em class="replaceable"><code>schema_name</code></em></span></dt><dd><p>
Name of an existing schema.
</p></dd><dt><span class="term"><code class="literal">SET ( <em class="replaceable"><code>publication_parameter</code></em> [= <em class="replaceable"><code>value</code></em>] [, ... ] )</code></span></dt><dd><p>
This clause alters publication parameters originally set by
<a class="xref" href="sql-createpublication.html" title="CREATE PUBLICATION"><span class="refentrytitle">CREATE PUBLICATION</span></a>. See there for more information.
</p></dd><dt><span class="term"><em class="replaceable"><code>new_owner</code></em></span></dt><dd><p>
The user name of the new owner of the publication.
</p></dd><dt><span class="term"><em class="replaceable"><code>new_name</code></em></span></dt><dd><p>
The new name for the publication.
</p></dd></dl></div></div><div class="refsect1" id="id-1.9.3.25.7"><h2>Examples</h2><p>
