Which reminds me. I really wish pg_basebackup let you specify an alternative compression handler. We've been using pigz on our systems because our database is so large. It cuts backup time drastically, from about 2.5 hours to 28 minutes.
Until a CPU can compress at the same speed it can read data from disk devices, that's going to continue to be a problem. Parallel compression is great.
So even after our recent upgrade, we've kept using our home-grown backup system. :(
