Use read streams in CREATE DATABASE when STRATEGY=WAL_LOG. While this doesn't significantly change runtime now, it arranges for STRATEGY=WAL_LOG to benefit automatically from future optimizations to the read_stream subsystem. For large tables in the template database, this does read 16x as many bytes per system call. Platforms with high per-call overhead, if any, may see an immediate benefit.
