Change the retry-loop in standby mode to also try restoring files from

pg_xlog directory. This is essential for replaying WAL records that were streamed from the master, after a standby server restart. If a corrupt record is seen in a file restored from the archive or streamed from the master, log it as a WARNING and keep retrying. If the corruption is permanent, and not just a glitch in the whatever copies the files to the archive or a network error not caught by CRC checks in TCP for example, we will keep retrying and logging the WARNING indefinitely. But that's better than shutting down completely, the standby is still useful for running read-only queries. In PITR the recovery ends at such a corrupt record, which is a bit questionable, but that's the behavior we had in previous releases and we don't feel like chaning it now. It does make sense for tools like pg_standby.
