My user account which is also the one that ran initdb and the one that
ran postgres. I discovered this when trying to work on a project I'd
started on arch linux where everything is peachy.

Ah, thanks for the tip. I will change over to that. But CREATE
EXTENSION gives the identical error:
postgres=# create extension plpython2u;
ERROR: could not load library
"/usr/local/lib/postgresql/plpython2.so": dlopen
(/usr/local/lib/postgresql/plpython2.so) failed: Cannot load specified

Ah, good point.
It turned out that the problem DLL was libpthread. I discovered this
using LD_DEBUG and worked around it with LD_PRELOAD.
Full output is below, so that hopefully this becomes searchable:
$ uname -a
OpenBSD localhost.localdomain 5.5 GENERIC.MP#315 amd64

This user must also own the server process.

You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.
Success. You can now start the database server using:
postgres -D data
or
pg_ctl -D data -l logfile start

But I do not understand why libpthread.so refuses to load if the
system knows it needs it. libpython2.7.so isn't preloaded like
libkrb5.so and friends, and that seems to load fine except for its
broken dependency.
Anyway, thanks for the tips; I'll take this to the OpenBSD maintainers now.
