Tom Lane 51e61b04f8 Ensure pg_ctl behaves sanely when data directory is not specified. 
Commit aaa6e1def2 introduced multiple hazards
in the case where pg_ctl is executed with neither a -D switch nor any
PGDATA environment variable.  It would dump core on machines which are
unforgiving about printf("%s", NULL), or failing that possibly give a
rather unhelpful complaint about being unable to execute "postgres -C",
rather than the logically prior complaint about not being told where the
data directory is.

Edmund Horner's report suggests that there is another, Windows-specific
hazard here, but I'm not the person to fix that; it would in any case only
be significant when trying to use a config-only PGDATA pointer.

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:

	http://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.  Changes between all PostgreSQL releases are recorded in the
file HISTORY.  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
http://www.postgresql.org/download/.  For more information look at our
web site located at http://www.postgresql.org/.
