psql will by default connect via a Unix socket, whereas the ODBC code
is evidently set up to connect via TCP/IP.  I bet if you try
"psql -h 10.10.29.11 ..." it will block too.

It could be a problem with your pg_hba.conf entry for local TCP
connections, but usually mistakes there don't result in a complete
hang.  I'm wondering whether kernel-level packet filtering is preventing
the connection request from going through.  If you've got any sort of
software firewall setup, check its rules.
