Tom Lane fbbd7edca8 Doc: adjust examples of EXTRACT() output to match current reality. 
EXTRACT(EPOCH), EXTRACT(SECOND), and some related cases print more
trailing zeroes than they used to.  This behavior change happened
with commit a2da77cdb (Change return type of EXTRACT to numeric),
and it was intentional according to the commit log:

    - Return values when extracting fields with possibly fractional
      values, such as second and epoch, now have the full scale that the
      value has internally (so, for example, '1.000000' instead of just
      '1').

It's been like that for two releases now, so while I suggested
changing this back, it's probably better to adjust the documentation
examples.

Per bug #17866 from Евгений Жужнев.  Back-patch to v14 where the
change came in.

PostgreSQL Database Management System
=====================================

This directory contains the source code distribution of the PostgreSQL
database management system.

PostgreSQL is an advanced object-relational database management system
that supports an extended subset of the SQL standard, including
transactions, foreign keys, subqueries, triggers, user-defined types
and functions.  This distribution also contains C language bindings.

PostgreSQL has many language interfaces, many of which are listed here:

	https://www.postgresql.org/download/

See the file INSTALL for instructions on how to build and install
PostgreSQL.  That file also lists supported operating systems and
hardware platforms and contains information regarding any other
software packages that are required to build or run the PostgreSQL
system.  Copyright and license information can be found in the
file COPYRIGHT.  A comprehensive documentation set is included in this
distribution; it can be read as described in the installation
instructions.

The latest version of this software may be obtained at
https://www.postgresql.org/download/.  For more information look at our
web site located at https://www.postgresql.org/.
