If more flexibility is wanted in this function, could it be an option
to consider a flavor like pg_stat_reset_shared(text[]), where it is
possible to specify a list of shared stats types to reset? Perhaps
there are no real use cases for it, just wanted to mention it anyway
regarding the fact that it could have benefits to refactor this code
to use a bitwise operator for its internals with bit flags for each
type.
