Merged patch series by Rafael Ávila de Espíndola:
The main advantage is that callers now don't have to construct
sstrings. It is also a 0.09% win in text size (from 41804308 to
41766484 bytes) and the tps reported by
perf_simple_query --duration 16 --smp 1 -m4G >> log 2>err
in 500 randomized runs goes up by 0.16% (from 162259 to 162517).
