Hi, As pointed out in http://www.postgresql.org/message-id/20160327232509.v5wgac5vskuse...@awork2.anarazel.de our backup tools (i.e. pg_basebackup, pg_dump[all]), currently don't make any efforts to ensure their output is durable.
I think for backup tools of possibly critical data, that's pretty much unaceptable. There's cases where we can't ensure durability (i.e. pg_dump | gzip > file), but it's out of our hands in that case.
