Fix possible "tuple concurrently updated" error in ALTER TABLE. When adding an inheritance parent to a table, an AccessShareLock on the parent isn't strong enough to prevent trouble, so take ShareUpdateExclusiveLock instead. Since this is a behavior change, albeit a fairly unobtrusive one, and since we have only one report from the field, no back-patch.
Report by Jon Nelson, analysis by Alvaro Herrera, fix by me.
