The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/16/bug-reporting.html Description:
Hello, in https://www.postgresql.org/docs/16/continuous-archiving.html#BACKUP-ARCHIVING-WAL the example given could be improved for Linux / Unix environment. As cp command is buffered it means it could return success although the data didn't reach the disk which puts backups at risk. I propose to use dd command with its fsync option. So the actual equivalent example would be : archive_command = 'dd if=%p of=/mnt/server/archivedir/%f bs=1M conv=fsync,excl status=none' # Unix What do you think ? Regards Gilles
