Tom Lane 471d55859c Adjust psql \d query to avoid use of @> operator.
It seems that the parray_gin extension has seen fit to introduce a
"text[] @> text[]" operator, which conflicts with the core
"anyarray @> anyarray" operator, causing ambiguous-operator failures
if the input arguments are coercible to text[] without being exactly
that type.  This strikes me as a bad idea, but it's out there and
people use it.  As of v10, that breaks psql's query that tries to
test "pg_statistic_ext.stxkind @> '{d}'", since stxkind is char[].
The best workaround seems to be to avoid use of that operator.
We can use a scalar-vs-array test "'d' = any(stxkind)" instead;
that's arguably more readable anyway.

Per report from Justin Pryzby.  Backpatch to v10 where this
query was added.

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/.
