Better look at the "ulimit" values the postmaster is started with;
you shouldn't be getting that out-of-memory error AFAICS, unless
there's a very restrictive ulimit on what an individual process can
allocate.

Thanks!

OpenBSD makes a _postgresql user on install and it is in the daemon class with the following values:

daemon:\
        :ignorenologin:\
        :datasize=infinity:\
        :maxproc=infinity:\
        :openfiles-cur=128:\
        :stacksize-cur=8M:\
        :localcipher=blowfish,8:\
        :tc=default:

The OpenBSD specific readme suggests making a special postgresql login class and bumping openfiles-cur to 768 but I don't see how that helps here. Would bumping stacksize also help?
