Peter Geoghegan a7b9d24e4e Make deduplication use number of key attributes.
Use IndexRelationGetNumberOfKeyAttributes() rather than
IndexRelationGetNumberOfAttributes() when determining whether or not two
index tuples are suitable for merging together into a single posting
list tuple.  This is a little bit tidier.  It brings affected code in
nbtdedup.c a little closer to similar, related code in nbtsplitloc.c.

=====================================

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

and functions.  This distribution also contains C language bindings.

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

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
