Posiblemente, el problemita no esta en los JDBC's sino el los sockets
Unix de postgresql...




doy esto  desde otra maquina ...


# psql -h icaro
Connection to database 'root' failed.
connectDB() failed: Is the postmaster running and accepting TCP/IP(with
-i) connections at 'icaro' on port '5432'?
# 




y para verificar, doy telnet desde otra maquina...



$ telnet zeus 5432
Trying 200.34.40.125...
telnet: Unable to connect to remote host: Connection refused
$ telnet icaro 5432
Trying 200.34.40.65...
telnet: Unable to connect to remote host: Connection refused
$ 



este es mi archivo de configuracion pg_hba localizado en
/usr/local/pgsql/data...


# The above would allow anyone anywhere except from 192.168.0.1 to
connect to
# any database under any username.

#host         all        192.168.0.0  255.255.255.0      ident    
omicron
#
# The above would allow users from 192.168.0.x hosts to connect to any
# database, but if e.g. Ident says the user is "bryanh" and he requests
to
# connect as Postgres user "guest1", the connection is only allowed if
# there is an entry for map "omicron" in pg_ident.conf that says
"bryanh" is 
# allowed to connect as "guest1".

# By default, allow anything over UNIX domain sockets and localhost.

local        all                                         trust
host         all         127.0.0.1     255.255.255.255   trust
host	     all	 0.0.0.0       255.255.255.255	 trust
