Thanks for looking again.

Couple tweaks:

+/* Phases of vacuum during which an error can occur. */

Can you say: "during which we report error context"
Otherwise it sounds like we've somehow precluded errors from happening anywhere
else, which I don't think we can claim.

In the commit messsage:
|The additional information displayed will be block number for errors
|occurred while processing heap and index name for errors occurred
|while processing the index.

=> error occurring

|This will help us in diagnosing the problems that occurred during a
|vacuum. For ex. due to corruption if we get some error while vacuuming,

=> problems that occur

Maybe it should say that this will help both 1) admins who have corruption due
to hardware (say); and, 2) developer's with corruption due to a bug.
