pg_restore is broken on 9.2 version.

Hi All,

Commit c59a1a89035674c6efacc596d652528cebba37ec don't allow non-positive
number
of jobs. Now on 9.2 number of jobs get assigned to opts->number_of_jobs. If
user don't specify any value -j then default value will be always 0. Which
will
lead to the "invalid number of parallel jobs" error.

if (opts->number_of_jobs <= 0)
{
fprintf(stderr, _("%s: invalid number of parallel jobs\n"),
progname);
exit(1);
}

Please find attach patch to initialize default value for number of jobs to
1.

Thanks,
