I don't really see how? I don't think listing only the current locklevel
really is an improvement and something like "SELECT ... FOR $locktype
cannot .." seem uncommon enough in pg error messages to be strange.
Now I aggree that listing all those locklevels isn't that nice, but I
don't really have a better idea.
