The command ALTER PUBLICATION
can change the attributes
of a publication.
The first three variants change which tables/schemas are part of the
publication. The SET
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
ADD
and DROP
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
ALTER SUBSCRIPTION ... REFRESH PUBLICATION
action on the
subscribing side in order to become effective. Note also that
DROP TABLES IN SCHEMA
will not drop any schema tables
that were specified using
FOR TABLE
/
ADD TABLE
, and 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 CREATE PUBLICATION. 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 TABLES IN SCHEMA
and
SET TABLES IN SCHEMA
to a publication requires the
invoking user to be a superuser.
To alter the owner, you must be able to SET ROLE
to the
new owning role, and that role must have CREATE
privilege on the database.
Also, the new owner of a
FOR ALL TABLES
or FOR TABLES IN SCHEMA
publication must be a superuser. However, a superuser can
change the ownership of a publication regardless of these restrictions.
Adding/Setting any schema when the publication also publishes a table with a column list, and vice versa is not supported.
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.
Optionally, a column list can be specified. See CREATE PUBLICATION 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 Warning: Combining Column Lists from Multiple Publications for details of potential problems when altering column lists.
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.
schema_name
Name of an existing schema.
SET ( publication_parameter
[= value
] [, ... ] )
This clause alters publication parameters originally set by CREATE PUBLICATION. See there for more information.
new_owner
The user name of the new owner of the publication.
new_name
The new name for the publication.
