- * AlterExtensionOwner_internal
- *
- * Internal routine for changing the owner of an extension.  rel must be
- * pg_extension, already open and suitably locked; it will not be closed.
- *
- * Note that this only changes ownership of the extension itself; it doesn't
- * change the ownership of objects it contains.  Since this function is
- * currently only called from REASSIGN OWNED, this restriction is okay because
- * said objects would also be affected by our caller.  But it's not enough for
- * a full-fledged ALTER OWNER implementation, so beware.
