<varlistentry id="sql-altertable-desc-owner-to">

<listitem>

This form changes the owner of the table, sequence, view, materialized view,
or foreign table to the specified user.
</para>
</listitem>
</varlistentry>
<varlistentry id="sql-altertable-replica-identity">
<term><literal>REPLICA IDENTITY</literal></term>
<listitem>
<para>
This form changes the information which is written to the write-ahead log
to identify rows which are updated or deleted.
In most cases, the old value of each column is only logged if it differs
from the new value; however, if the old value is stored externally, it is
always logged regardless of whether it changed.
This option has no effect except when logical replication is in use.
<variablelist>
<varlistentry id="sql-altertable-replica-identity-default">
<term><literal>DEFAULT</literal></term>
<listitem>
<para>
Records the old values of the columns of the primary key.
This is the default for non-system tables.
When there is no primary key, the behavior is the same as <literal>NOTHING</literal>.
</para>
</listitem>
</varlistentry>
<varlistentry id="sql-altertable-replica-identity-using-index">
<term><literal>USING INDEX <replaceable class="parameter">index_name</replaceable></literal></term>
<listitem>
<para>
Records the old values of the columns covered by the named index,
that must be unique, not partial, not deferrable, and include only
columns marked <literal>NOT NULL</literal>. If this index is
dropped, the behavior is the same as <literal>NOTHING</literal>.
</para>
</listitem>
</varlistentry>
<varlistentry id="sql-altertable-replica-identity-full">
<term><literal>FULL</literal></term>
<listitem>

<varlistentry id="sql-altertable-replica-identity-nothing">

<varlistentry id="sql-altertable-desc-rename">
<term><literal>RENAME</literal></term>
<listitem>
<para>
The <literal>RENAME</literal> forms change the name of a table
(or an index, sequence, view, materialized view, or foreign table), the
name of an individual column in a table, or the name of a constraint of
the table. When renaming a constraint that has an underlying index,
the index is renamed as well.
There is no effect on the stored data.
</para>
</listitem>
</varlistentry>
<varlistentry id="sql-altertable-desc-set-schema">
<term><literal>SET SCHEMA</literal></term>
<listitem>
<para>
This form moves the table into another schema. Associated indexes,
constraints, and sequences owned by table columns are moved as well.
</para>
</listitem>

<varlistentry id="sql-altertable-attach-partition">
<term><literal>ATTACH PARTITION <replaceable class="parameter">partition_name</replaceable> { FOR VALUES <replaceable class="parameter">partition_bound_spec</replaceable> | DEFAULT }</literal></term>
<listitem>
<para>
This form attaches an existing table (which might itself be partitioned)
as a partition of the target table. The table can be attached
as a partition for specific values using <literal>FOR VALUES</literal>
or as a default partition by using <literal>DEFAULT</literal>.
