At some point during the development of the patch there was a reason (which I
cannot remember right now) for the declaration being in hba.h, but I clearly
missed moving it when that no longrer applied. No objections to the patch,
thanks!

It's following the naming convention of load_hba() which reads pg_hba.conf, and
load_ident() which reads pg_ident.conf - thus load_hosts() for the function
that reads pg_hosts.conf. Perhaps load_pg_hosts_conf() or load_hosts_config()
would convey more meaning?
