Commit8f427187dbimproved performance by remembering relation stats as native types rather than issuing a new query for each relation. Using native types is fine for integers like relpages; but reltuples is floating point. The commit controllled for that complexity by using setlocale(LC_NUMERIC, "C"). After that, Alexander Lakhin found a problem in pg_strtof(), fixed in00d61a08c5. While we aren't aware of any more problems with that approach, it seems wise to just use a string the whole way for floating point values, as Corey's original patch did, and get rid of the setlocale(). Integers are still converted to native types to avoid wasting memory.
