ALTER LARGE OBJECT(7) PostgreSQL 16.3 Documentation ALTER LARGE OBJECT(7)

ALTER_LARGE_OBJECT - change the definition of a large object

ALTER LARGE OBJECT large_object_oid OWNER TO { new_owner | CURRENT_ROLE | CURRENT_USER | SESSION_USER }

ALTER LARGE OBJECT changes the definition of a large object.

You must own the large object to use ALTER LARGE OBJECT. To alter the owner, you must also be able to SET ROLE to the new owning role. (However, a superuser can alter any large object anyway.) Currently, the only functionality is to assign a new owner, so both restrictions always apply.

large_object_oid

OID of the large object to be altered

new_owner

The new owner of the large object

There is no ALTER LARGE OBJECT statement in the SQL standard.
