Folks are asking me off-list:

RE: http://archives2.us.postgresql.org/pgsql-general/2001-10/msg00448.php
"binding tcp connections to certain addresses"

Will:
Did you ever receive a response or resolution to this problem? I
am in the same situation, trying to bind the same IP's.

If you can lend a hand, it would be most greatly appreciated!

Thanks, in advance!

i did find out that /etc/postgresql/postgresql.conf can contain
a line such as

virtual_host = '127.0.0.1'

using SINGLE QUOTES to delimit the IP address -- but successive
instances of that line such as

virtual_host = '127.0.0.1'
virtual_host = '192.168.1.1'

the latter will override/wipe out the former. i've tried taking
blind stabs in the dark such as

virtual_host = '127.0.0.1','192.168.1.1'
virtual_host = '127.0.0.1,192.168.1.1'

to no avail (errors in /var/log/postgresql.log):

FATAL 1: postgresql.conf:41: syntax error, token=","
FATAL: StreamServerPort: gethostbyname(127.0.0.1,192.168.1.1) failed

any nudges are welcome. :)

(there's always the firewall/ipchains/iptables route, but surely
there's a postgresql-specific way to turn listening on and off
for several addresses?)

Nope, not unless you want to start a separate postmaster for each such
address.

Not real sure that I see the value of binding to N addresses rather
than to no-particular-address ...
