Oh, I had forgotten we still had that wart in the grammar.
It doesn't actually work:

		else if (strcmp(defel->defname, "sysid") == 0)
		{
			ereport(NOTICE,
					(errmsg("SYSID can no longer be specified")));
		}

Not sure if it's better to try to make that work again than to add
another hack in pg_upgrade_support.  On the whole that's a keyword
I'd rather see us drop someday soon.
