Add block information in error context of WAL REDO apply loop Providing this information can be useful for example when diagnosing problems related to recovery conflicts or for recovery issues without having to go through the output generated by pg_waldump to get some information about the blocks a WAL record works on. The block information is printed in the same format as pg_waldump. This already existed in xlog.c for debugging purposes with -DWAL_DEBUG, so adding the block information in the callback has required just a small refactoring.
