Add write_to_file to PgStat_KindInfo for pgstats kinds This new field controls if entries of a stats kind should be written or not to the on-disk pgstats file when shutting down an instance. This affects both fixed and variable-numbered kinds.
This is useful for custom statistics by itself, and a patch is under discussion to add a new builtin stats kind where the write of the stats is not necessary. All the built-in stats kinds, as well as the two custom stats kinds in the test module injection_points, set this flag to "true" for now, so as stats entries are written to the on-disk pgstats file.
