I am changing from 7.2 to 8.0 and have both installed now on various Linux machines. When I use the psql command line interface with a -h hostname, the connection time from 7.2 is instant while the connection time from 8.0 is 15 seconds. My assumption is that 7.2 checks the /etc/hosts file first and if unable to find the specified host it reverts to a DNS lookup, and the 8.0 is just the opposite. Is this a correct assumption, and if so, can I modify 8.0 to behave as 7.2 does?
