alter_schema ::= ALTER SCHEMA schema_name 
                 { RENAME TO new_name
                   | OWNER TO { new_owner
                                | CURRENT_USER
                                | SESSION_USER } }

Semantics

• ALTER SCHEMA changes the definition of a schema.
• In order to use ALTER SCHEMA, you need to be the owner of the schema.
• Renaming a schema requires having the CREATE privilege for the database.
• If you want to change the owner, you must also be a direct or indirect member of the new owning role, and you need to have the CREATE privilege for the database. (It's worth noting that superusers possess these privileges by default.)

alter_schema

ALTER SCHEMA schema_name

Specify the name of the schema (schema_name). An error is raised if a schema with that name does not exist in the current database.

schema_name

The name of the schema.

RENAME TO new_name

Rename the schema.

new_name

Schema names must not begin with pg_. The attempt to create a schema with such a name, or to rename an existing schema to have such a name, causes an error.

OWNER TO (new_owner | CURRENT_USER | SESSION_USER)

Change the owner of the schema.

new_owner

The new owner of the schema.

CURRENT_USER

Username of current execution context.

SESSION_USER

Username of current session.

Examples

Create a simple schema.

yugabyte=# CREATE SCHEMA schema22;

CREATE SCHEMA

Rename the schema.

yugabyte=# ALTER SCHEMA schema22 RENAME TO schema25;

ALTER SCHEMA

yugabyte=# \dn

   List of schemas
   Name   |  Owner   
----------+----------
 public   | postgres
 schema25 | yugabyte
(2 rows)

Change the owner of the schema.

yugabyte=# ALTER SCHEMA schema25 OWNER TO postgres;

ALTER SCHEMA

yugabyte=# \dn

   List of schemas
   Name   |  Owner   
----------+----------
 public   | postgres
 schema25 | postgres
(2 rows)
