Peter Geoghegan 1e07f5e0a1 Remove overzealous _bt_split() assertions. 
_bt_split() is passed NULL as its insertion scankey for internal page
splits.  Two recently added Assert() statements failed to consider this,
leading to a crash with pg_upgrade'd BREE_VERSION < 4 indexes.  Remove
the assertions.

The assertions in question were added by commit 0d861bbb, which added
nbtree deduplication.  It would be possible to fix the assertions
directly instead, but they weren't adding much anyway.

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/.
