Tom Lane bb20f2c80d Doc: warn that timezone abbreviations don't work in recovery_target_time.
Moving this setting into the main configuration file was ill-considered,
perhaps, because that typically causes it to be set before
timezone_abbreviations has been set.  Which in turn means that zone
abbreviations don't work, only full zone names.

We could imagine hacking things so that such cases do work, but the
stability of the hack would be questionable, and the value isn't really
that high.  Instead just document that you should use a numeric zone
offset or a full zone name.

Per bug #16404 from Reijo Suhonen.
Back-patch to v12 where this was changed.

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/.
