BUG #8590: unlimit_core_size failed in `make check`.

The following bug has been logged on the website:

Bug reference:      8590

$ make check

mkdir ./testtablespace

--top-builddir=../../..   --dlpath=.  --schedule=./parallel_schedule
pg_regress: could not set core size: disallowed by hard limit
============== creating temporary installation        ==============
============== initializing database system           ==============


Here's the line that generates the error message from pg_regress.c (circa
line 160):


getrlimit(RLIMIT_CORE, &lim);
if (lim.rlim_max == 0)
{
    fprintf(stderr,
        _("%s: could not set core size: disallowed by hard limit\n"),
        progname);
    return;
}


Sorry if this is a spurious. Searching for the message returned references
to source code; and not a bug report or mailing list message on the best way
to fix it for Postgres.
