- Testing compression of PostgreSQL backups with xz and gzip:
```
$ time xz -c cgspace_2018-12-19.backup > cgspace_2018-12-19.backup.xz
xz -c cgspace_2018-12-19.backup > cgspace_2018-12-19.backup.xz 48.29s user 0.19s system 99% cpu 48.579 total
$ time gzip -c cgspace_2018-12-19.backup > cgspace_2018-12-19.backup.gz
gzip -c cgspace_2018-12-19.backup > cgspace_2018-12-19.backup.gz 2.78s user 0.09s system 99% cpu 2.899 total
$ ls -lh cgspace_2018-12-19.backup*

-rw-r--r-- 1 aorth aorth 93M Dec 20 11:35 cgspace_2018-12-19.backup.xz
```
