Move information about pgstats kinds into its own header pgstat_kind.h
This includes all the definitions for the various PGSTAT_KIND_* values,the range allowed for custom stats kinds and some macros related allthat.One use-case behind this split is the possibility to use thisinformation for frontend tools, without having to rely on pgstat.h and abackend footprint.Author: Michael PaquierReviewed-by: Bertrand DrouvotDiscussion:https://postgr.es/m/Z24fyb3ipXKR38oS@paquier.xyz
