Filing an issue for this TODO:

cockroach/pkg/sql/stats/stats_cache.go

Lines 811 to 812 in d7135c3

// TODO(faizaanmadhani): Wrap merging behind a boolean so
// that it can be turned off.

Now that we've introduced merging of partial statistics, we should add one or more variables to disable it if necessary.
