Okey, I'll revise the patch; create also the directory which is
referenced by symlink if not present.

You mean having assign_pgstat_temp_directory() create the
directory instead of pgstat_start()? In this case, the directory is
created automatically not only at the beginning but also when
a configuration file is reloaded. This seems to be better behavior.
One problem of this is that some directories may be created
unexpectedly if stats_temp_directory is specified at multiple
locations. It's because assign_hook is called for each setting.
