[PATCH] ident authentication fails on kFreeBSD/x86-64 due to wrong struct size

Hello PostgreSQL developers,

I got this report in http://bugs.debian.org/612888 about ident failure
on the Debian kFreeBSD kernel on 64 bit. The sizeof(struct cmsgcred)
is 84 on kfrebsd-amd64, there is no reason for padding it at the end
to 8-byte boundary by kernel. However, the process is blocking on
receiving those extra 4 bytes, which will never come.

Petr Salinger <Petr(dot)Salinger(at)seznam(dot)cz> sent a straightforward patch
for this, I turned it into a git-formatted patch for your convenience.

Thanks,

Martin

Package: postgresql
Version: 8.4.7-0squeeze2
Severity: important

After default installation, postgres denies access to postgres user:

root(at)netmon:~# su - postgres
postgres(at)netmon:~$ psql template1
psql: FATAL: Ident authentication failed for user "postgres"

This happens on kFreeBSD flavour only (AFAIK)
