<title>Description</title>

|
|
<para>
|
|
The command <command>ALTER PUBLICATION</command> can change the attributes
|
|
of a publication.
|
|
</para>
|
|
|
|
<para>
|
|
The first three variants change which tables are part of the publication.
|
|
The <literal>SET TABLE</literal> clause will replace the list of tables in
|
|
the publication with the specified one. The <literal>ADD TABLE</literal>
|
|
and <literal>DROP TABLE</literal> clauses will add and remove one or more
|
|
tables from the publication. Note that adding tables to a publication that
|
|
is already subscribed to will require a <literal>ALTER SUBSCRIPTION
|
|
... REFRESH PUBLICATION</literal> action on the subscribing side in order
|
|
to become effective.
|
|
</para>
|
|
|
|
<para>
|
|
The fourth variant of this command listed in the synopsis can change
|
|
all of the publication properties specified in
|
|
<xref linkend="sql-createpublication"/>. Properties not mentioned in the
|
|
command retain their previous settings.
|
|
</para>
|
|
|
|
<para>
|
|
The remaining variants change the owner and the name of the publication.
|
|
</para>
|
|
|
|
<para>
|
|
You must own the publication to use <command>ALTER PUBLICATION</command>.
|
|
To alter the owner, you must also be a direct or indirect member of the new
|
|
owning role. The new owner must have <literal>CREATE</literal> privilege on
|
|
the database. Also, the new owner of a <literal>FOR ALL TABLES</literal>
|
|
publication must be a superuser. However, a superuser can change the
|
|
ownership of a publication while circumventing these restrictions.

Name of an existing table. If <literal>ONLY</literal> is specified before the

|
table name, only that table is affected. If <literal>ONLY</literal> is not
|
|
specified, the table and all its descendant tables (if any) are
|
|
affected. Optionally, <literal>*</literal> can be specified after the table
|
|
name to explicitly indicate that descendant tables are included.
