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
../../../src/test/regress/pg_regress --inputdir=. --temp-install=./tmp_check
--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.
