Name an implementation of std::vector that doesn't do this.

In this case, you'd do that to avoid the need for a separate COUNT(*)
query. If you have a pretty good idea already how many records to
expect, reserving that amount plus some small fudge factor will probably
run faster than doing two queries so you can reserve only exactly what
is required.
