This switches the pgstats write code to use durable_rename() rather than rename(). This ensures that the stats file's data is durable when the statistics are written, which is something only happening at shutdown now with the checkpointer doing the job. This could cause the statistics to be lost even after PostgreSQL is shut down, should a host failure happen, for example.
