Sure, its call convention is standardized. But I see nothing in POSIX
saying whether it returns a FQDN or just some random name. In any
case, the bigger issue is that I don't really want us to expose a
function defined as "whatever gethostname() says". I think there will
be portability issues on some platforms, and I am dubious that that
definition is what people would want.
One concrete reason why I am doubtful about this is the case of
multiple PG servers running on the same machine. gethostname()
will be unable to distinguish them.
