Maybe i am missing something, i use the same command to connect to it from 
localhost "psql -d database -h localhost" and in the pcap files i have captured 
the protocol it is clear (with "ssl = false" or "ssl = true" either), but in the 
debian machine with "ssl = true" in postgresql.conf you can see in the pcap file 
big time jumps between data packets, psql commandline enables automatically ssl 
if the server supports it? but if this is the case i should see encrypted 
traffic in pcap files, and the problem should be the same in Arch Linux, no? If 
you want that i make a local test explain me the steps and i will try here.
