ALTER LARGE [OBJECT(7)](https://www.chedong.com/phpMan.php/man/OBJECT/7/markdown)              PostgreSQL 14.23 Documentation              ALTER LARGE [OBJECT(7)](https://www.chedong.com/phpMan.php/man/OBJECT/7/markdown)



## 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
       a direct or indirect member of 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.
