-Fc doesn't do anything different with floats than text dumps do.
pg_dump (in all modes) uses the extra_float_digits setting to try and
get a value that restores exactly. There have been issues with this in
the past (the limit of extra_float_digits had to be raised from 2 to 3,
iirc), but if it's happening now then that should probably be considered
a bug.
