Teodor Sigaev 62e0ade9aa Fix lossy KNN GiST when ordering operator returns non-float8 value. 
KNN GiST with recheck flag should return to executor the same type as ordering
operator, GiST detects this type by looking to return type of function which
implements ordering operator. But occasionally detecting code works after
replacing ordering operator function to distance support function.
Distance support function always returns float8, so, detecting code get float8
instead of actual return type of ordering operator.

Built-in opclasses don't have ordering operator which doesn't return
non-float8 value, so, tests are impossible here, at least now.

Backpatch to 9.5 where lozzy KNN was introduced.

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:

	http://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
http://www.postgresql.org/download/.  For more information look at our
web site located at http://www.postgresql.org/.
