Tom Lane 1dd6700f44 Fix under-parenthesized display of AT TIME ZONE constructs. In commit `40c24bfef`, I forgot to use get_rule_expr_paren() for the arguments of AT TIME ZONE, resulting in possibly not printing parens for expressions that need it. But get_rule_expr_paren() wouldn't have gotten it right anyway, because isSimpleNode() hadn't been taught that COERCE_SQL_SYNTAX parent nodes don't guarantee sufficient parentheses. Improve all that. Also use this methodology for F_IS_NORMALIZED, so that we don't print useless parens for that. In passing, remove a comment that was obsoleted later. Per report from Duncan Sands. Back-patch to v14 where this code came in. (Before that, we didn't try to print AT TIME ZONE that way, so there was no bug just ugliness.)

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/.
