Increase the maximum value of extra_float_digits to 3, and have pg_dump

use that value when the backend is new enough to allow it.  This responds
to bug report from Keh-Cheng Chu pointing out that although 2 extra digits
should be sufficient to dump and restore float8 exactly, it is possible to
need 3 extra digits for float4 values.
