Hi Tom,

Thanks for your advice. I'm indeed only able to connect to the cluster from outside the chroot using unix sockets like:

$ psql --host /jail/tmp --port 5421 mydb

If I try and force a TCP/IP connexion, it fails with:
$ psql --host localhost --port 5421 mydb
psql: could not connect to server: Connection refused
        Is the server running on host "localhost" and accepting
        TCP/IP connections on port 5421?
FATAL:  no pg_hba.conf entry for host "192.168.1.103", user "santiago", database "santiago"

I have mounted /dev, /proc and /sys inside the chroot. What else could be necessary to allow TCP/IP connections to postgresql?

Regards

Apparently there's some aspect of your chroot setup that breaks TCP
connections to "localhost".  You need to fix that ...
