Avoid performing unnecessary roundingof<link

linkend="datatype-float"><type>REAL</type></link> and <type>DOUBLE

PRECISION</type> values (Andrew Gierth)

Improve performance by changing the default numberoftrailing digits

output for <linklinkend="datatype-float"><type>REAL</type></link>

and <type>DOUBLEPRECISION</type> values (Andrew Gierth)

</para>

<para>

This dramatically speeds up processing of floating-point

values but causes additional trailing digits to

potentially be displayed. Users wishing to have output

that is rounded to match the previous behavior can set <link

linkend="guc-extra-float-digits"><literal>extra_float_digits=0</literal></link>,

which is no longer the default.

Previously, float values were output rounded to 6 or 15 decimals

by default. Now, only the number of digits required to preserve

the exact binary value is output. The previous behavior can be

restored by setting <xref linkend="guc-extra-float-digits"/> to zero.
