Tom Lane e1c056cc4d Avoid low-probability regression test failures in timestamp[tz] tests.
If the first transaction block in these tests were entered exactly
at midnight (California time), they'd report a bogus failure due
to 'now' and 'midnight' having the same values.  Commit 8c2ac75c5
had dismissed this as being of negligible probability, but we've
now seen it happen in the buildfarm, so let's prevent it.  We can
get pretty much the same test coverage without an it's-not-midnight
assumption by moving the does-'now'-work cases into their own test step.

While here, apply commit 47169c255's s/DELETE/TRUNCATE/ change to
timestamptz as well as timestamp (not sure why that didn't
occur to me at the time; the risk of failure is the same).

Back-patch to all supported branches, since the main point is
to get rid of potential buildfarm failures.

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/.
