OpenBSD ports post-installation gives core dump?

 >>I followed the instructions exactly and got a core dump!

Solved:

For those OpenBSD people, your kernel needs to have these options in your
kernel-configuration file:

# PostgreSQL NEEDS THIS
option          SYSVMSG         # System V-like message queues
option          SYSVSEM         # System V-like semaphores
option          SYSVSHM         # System V-like memory sharing
