I found this patch in my local repo that I wrote some weeks or months

pinpoint what XLog record in a long sequence of WAL files was causing a
problem, and the displaying the prev pointer in errcontext made finding
it much easier -- I could correlate it with pg_xlogdump output, I think.

Seems like a good idea, but why print the prev pointer, and not the location of the record itself?
