Tom Lane 3c2313f481 Change the pgstat logic so that the stats collector writes the stats file only ... upon requests from backends, rather than on a fixed 500msec cycle. (There's still throttling logic to ensure it writes no more often than once per 500msec, though.) This should result in a significant reduction in stats file write traffic in typical scenarios where the stats are demanded only infrequently. This approach also means that the former difficulty with changing stats_temp_directory on-the-fly has gone away, so remove the caution about that as well as the thrashing we did to minimize the trouble window. In passing, also fix pgstat_report_stat() so that we will send a stats message if we have function call stats but not table stats to report; this fixes a bug in the recent patch to support function-call stats.
