## Which issue does this PR close? N/A ## Rationale for this change We can easily specify the correct capacity for the result vector in `project_statistics`. Profiling shows that this reduces total allocated bytes for planning TPC-H Q13 by ~1.7%, or ~17 kB out of ~1.03MB of allocations. Probably too small to show up in a measurement of elapsed duration, but doesn't hurt. ## What changes are included in this PR? * Specify vector capacity in `project_statistics` ## Are these changes tested?
