You should use the postgresql driver that is provided by the
distribution you are running. If you are running windows download the exe.

So for Ubuntu:

apt-get install odbc-postgresql

odbc-postgresql is the driver
unixODBC is the driver manager.

So:

apt-get install unixodbc

Essentially yes. THe psqlodbc is probably more current but don't make
your life difficult.

  If so, is this better than the unixodbc

No. Use unixODBC.

Here are example working files:

/etc/odbc.ini:

I am curious why you are using ODBC to connect to PostgreSQL if you are
on Dapper? Are you using Open Office or somethign like that?
