BTW, after committing this I re-reviewed the thread and realized that
actually this problem is strictly cosmetic. The net effect of the
configure bug is is that it (1) doesn't set HAVE_SYS_UCRED_H and
as a consequence (2) doesn't set HAVE_STRUCT_CMSGCRED. However,
that's only examined in one place in libpq, which says:
* Note: this is dead code as of Postgres 9.1, because current backends will
* never send this challenge. But we must keep it as long as libpq needs to
* interoperate with pre-9.1 servers. It is believed to be needed only on
* Debian/kFreeBSD (ie, FreeBSD kernel with Linux userland, so that the
* getpeereid() function isn't provided by libc).
So on an OpenBSD build that code wouldn't be used anyway (not even
when talking to a pre-9.1 server, if I'm interpreting the comment
correctly).
