Thread: Corrupted WAL during recovery from archived log

Hi,
I'm writing some paper about instance recovery and I'm wondering how
PostgreSQL act when find a corrupted archived WAL during the restore
command.
I found that when instance recovery starts the zero_damaged_pages is
set to true.
This parameter affect only data files with corrupted pages or even wal
pages that are zeroed before going on data file?


Thanks in advance
Kind regards
Federico
