Peter Eisentraut e59fcbd712 Simplify information schema check constraint deparsing
The computation of the column
information_schema.check_constraints.check_clause used
pg_get_constraintdef() plus some string manipulation to get the check
clause back out.  This ended up with an extra pair of parentheses,
which is only an aesthetic problem, but also with suffixes like "NOT
VALID", which don't belong into that column.  We can fix both of these
problems and simplify the code by just using pg_get_expr() instead.

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/.
