nixos/postgresqlBackup: add --rsyncable to compression programs
The --rsyncable option changes the behavior of gzip/zstd so that the resulting files can be incrementally backed up easily. Tools like Borg, rsync and xdelta can make use their deduplication/diff mechanisms more easily. In my local testing, this resulted in a 2% size increase for backup files. Signed-off-by: Sefa Eyeoglu <contact@scrumplex.net> (cherry picked from commit 40c3d65bdff49b818073d7c92cf0ec6d7fab2bba)
