Jeff Davis 1852aea3f5 Don't convert to and from floats in pg_dump. 
Commit 8f427187db improved 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 in 00d61a08c5.

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.
