PAM isn't supported on all of our platforms and, really, even where we
do support it, it's frankly beyond impractical to actually use the PAM
modules because they expect to be run as root, which we don't do.

I can understand that you're not excited about it, and I'm not keen to
reinvent all of PAM (there's an awful lot of it which we really don't
need), but there are features that happen to also exist in PAM (and
Kerberos, and LDAP, and RADIUS, and...) that we really should have in
our own password-based authentication system because our users are
expecting them.  Looking at the various forks of PG that are out there
shows that quite clearly, I don't imagine they implemented these
features out of pure fun, and they obviously also realized that trying
to actually use PAM from PG was ultimately a bad idea.

Thanks!
