Stephen Frost e72059f375 pg_restore: Don't allow non-positive number of jobs 
pg_restore will currently accept invalid values for the number of
parallel jobs to run (eg: -1), unlike pg_dump which does check that the
value provided is reasonable.

Worse, '-1' is actually a valid, independent, parameter (as an alias for
--single-transaction), leading to potentially completely unexpected
results from a command line such as:

  -> pg_restore -j -1

Where a user would get neither parallel jobs nor a single-transaction.

Add in validity checking of the parallel jobs option, as we already have
in pg_dump, before we try to open up the archive.  Also move the check
that we haven't been asked to run more parallel jobs than possible on
Windows to the same place, so we do all the option validity checking
before opening the archive.

Back-patch all the way, though for 9.2 we're adding the Windows-specific
check against MAXIMUM_WAIT_OBJECTS as that check wasn't back-patched
originally.

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.  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/.
