>extra_float_digits</A
> setting controls the
      number of extra significant digits included when a floating point
      value is converted to text for output.  With the default value of
      <TT
CLASS="LITERAL"
>0</TT
>, the output is the same on every platform
      supported by PostgreSQL.  Increasing it will produce output that
      more accurately represents the stored value, but may be unportable.
