Sets the directory to store temporary statistics data in. This can be a
path relative to the data directory or an absolute path. The default is
<filename>pg_stat_tmp</filename>. Pointing this at a RAM based filesystem
will decrease physical I/O requirements and can lead to increased
performance. If this parameter is changed when the system is running,
there is a small window of time until the new file has been written
during which the statistics functions might return no information.
