change the definition of a publication
ALTER PUBLICATION name ADD publication_object [, ...]
ALTER PUBLICATION name SET publication_object [, ...]
ALTER PUBLICATION name DROP publication_object [, ...]
ALTER PUBLICATION name SET ( publication_parameter [= value] [, ... ] )
ALTER PUBLICATION name OWNER TO { new_owner | CURRENT_ROLE | CURRENT_USER | SESSION_USER }
ALTER PUBLICATION name RENAME TO new_name
where publication_object is one of:
TABLE [ ONLY ] table_name [ * ] [ WHERE ( expression ) ] [, ... ]
SEQUENCE sequence_name [, ... ]
ALL TABLES IN SCHEMA { schema_name | CURRENT_SCHEMA } [, ... ]
ALL SEQUENCES IN SCHEMA { schema_name | CURRENT_SCHEMA } [, ... ]
Description
The command ALTER PUBLICATION can change the attributes
of a publication.
The first three variants change which objects (tables, sequences or schemas)
are part of the publication. The SET clause will replace
the list of objects in the publication with the specified list; the existing
objects that were present in the publication will be removed.
The ADD and DROP clauses will add and
remove one or more objects from the publication. Note that adding objects
to a publication that is already subscribed to will require an
ALTER SUBSCRIPTION ... REFRESH PUBLICATION action on the
subscribing side in order to become effective. Note also that the combination
of DROP with a WHERE clause is not
allowed.
The fourth variant of this command listed in the synopsis can change
all of the publication properties specified in
. Properties not mentioned in the
command retain their previous settings.
The remaining variants change the owner and the name of the publication.
You must own the publication to use ALTER PUBLICATION.
Adding a table to a publication additionally requires owning that table.
The ADD ALL TABLES IN SCHEMA and
SET ALL TABLES IN SCHEMA to a publication requires the
invoking user to be a superuser. To alter the owner, you must also be a
direct or indirect member of the new owning role. The new owner must have
CREATE privilege on the database. Also, the new owner
of a FOR ALL TABLES or FOR ALL TABLES IN
SCHEMA publication must be a superuser. However, a superuser can
change the ownership of a publication regardless of these restrictions.
Adding/Setting a table that is part of schema specified in
ALL TABLES IN SCHEMA, adding/setting a schema to a
publication that already has a table that is part of the specified schema or
adding/setting a table to a publication that already has a table's schema as
part of the specified schema is not supported.
Parameters
name
The name of an existing publication whose definition is to be altered.
table_name
Name of an existing table. If ONLY is specified before the
table name, only that table is affected. If ONLY is not
specified, the table and all its descendant tables (if any) are
affected. Optionally, * can be specified after the table
name to explicitly indicate that descendant tables are included.
If the optional WHERE clause is specified, rows for
which the expression
evaluates to false or null will not be published. Note that parentheses
are required around the expression. The
expression is evaluated with
the role used for the replication connection.
sequence_name
Name of an existing sequence.
schema_name
Name of an existing schema.
SET ( publication_parameter [= value] [, ... ] )
This clause alters publication parameters originally set by
. See there for more information.

The user name of the new owner of the publication.
new_name
The new name for the publication.
