Currently, pg_stat_reset_shared() can use an argument to specify the target of statistics to reset, doing nothing for NULL as it is strict. This patch adds to pg_stat_reset_shared() the possibility to reset all the stats types already handled in this function rather than do nothing if the argument value given is NULL or if nothing is specified (proisstrict is switched to false). Like previously, SLRUs are not included in what gets reset. The idea to use NULL or no argument to control if all the shared stats already covered by this function should be reset has been proposed by Andres Freund. Bump catalog version.
