.SH "DESCRIPTION"
.PP
\fBALTER LARGE OBJECT\fR
changes the definition of a large object\&.
.PP
You must own the large object to use
\fBALTER LARGE OBJECT\fR\&. 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\&.
.SH "PARAMETERS"
.PP
\fIlarge_object_oid\fR
.RS 4
OID of the large object to be altered
.RE
.PP
\fInew_owner\fR
.RS 4
The new owner of the large object
.RE
.SH "COMPATIBILITY"
.PP
There is no
\fBALTER LARGE OBJECT\fR
statement in the SQL standard\&.
