Alvaro Herrera 815ef2f568 Don't constraint-exclude partitioned tables as much
We only need to invoke constraint exclusion on partitioned tables when
they are a partition, and they themselves contain a default partition;
it's not necessary otherwise, and it's expensive, so avoid it.  Also, we
were trying once for each clause separately, but we can do it for all
the clauses at once.

While at it, centralize setting of RelOptInfo->partition_qual instead of
computing it in slightly different ways in different places.

Per complaints from Simon Riggs about 4e85642d935e; reviewed by Yuzuko
Hosoya, Kyotaro Horiguchi.

Author: Amit Langote.  I (Álvaro) again mangled the patch somewhat.

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/.
