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

yugabyte=# CREATE SCHEMA schema22;
CREATE SCHEMA
Rename the schema.
yugabyte=# ALTER SCHEMA schema22 RENAME TO schema25;
