Rsync is popular with Postgres users, but I don't understand how they
are using the default check mode (file size, modification time) to
synchronize shut-down data directories?  It seems they would have to use
--checksum because it is too easy for files to change in the same
second, and for a backend to write into the middle of a file.

Is everyone who is using rsync with Postgres also using --checksum mode?
