ALTER LARGE OBJECT(7) PostgreSQL 16.2 Documentation ALTER LARGE OBJECT(7) NAME ALTER_LARGE_OBJECT - change the definition of a large object SYNOPSIS ALTER LARGE OBJECT large_object_oid OWNER TO { new_owner | CURRENT_ROLE | CURRENT_USER | SESSION_USER } DESCRIPTION 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. PARAMETERS large_object_oid OID of the large object to be altered new_owner The new owner of the large object COMPATIBILITY There is no ALTER LARGE OBJECT statement in the SQL standard.
