client ssl

Good day ppl,
I'm sorry if my question is a little bit stupid but, i have search already
an answer on Internet.
I have start postgres 7.1 with ssl suport with out any problems, i have
set on pg_hda.conf like this:

#local        all                                           trust
hostssl         all         127.0.0.1     255.255.255.255     trust
#host         all         127.0.0.1     255.255.255.255     trust

and i have try
psql -h 127.0.0.1 teste
what is working if i set
host         all         127.0.0.1     255.255.255.255     trust
So what's hapening, why psql cannot connect to postgres, it dosen't
support ssl or what???

Thanks alot for reading this.
