ALTER LARGE OBJECT(7)              PostgreSQL 16.14 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.
