I haven't checked whether pg_hba.conf rules are reloaded, but `pg_ctl reload' can re-read some settings without a postmaster restart. So you might be able to disallow access in pg_hba then reload. I'd be curious to know if that works and if/how it affects existing connections - though I can always test it myself.
Yes, a pg_ctl reload will reload pg_hba.conf and, iirc, it does not kill any existing connections as the values in that file are checked at time of connection, not time of config load.
