For the base config tools:

sudo apt-get install unixodbc-bin unixodbc odbcinst1debian1

For Postgres

sudo apt-get install odbc-postgresql

Use the template file provided to setup the odbc driver entries:

sudo odbcinst -i -d -f /usr/share/psqlodbc/odbcinst.ini.template

And this sets up the sample DSNs. (all one line)

 sudo odbcinst -i -s -l  -n adyoung-pg -f /usr/share/doc/odbc-postgresql/examples/odbc.ini.template

Then modify /etc/odbc.ini to suit your DB.

For MSSQL Server and Sybase:

 sudo apt-get install tdsodbc

sudo odbcinst -i -d -f /usr/share/doc/freetds-dev/examples/odbcinst.ini

Unfortunately, this does not have a sample ODBC setup template.
