From:

https://www.mankier.com/1/isql

"DSN

     The Data Source Name (DSN) used to connect to the SQL database. 
unixODBC looks for the specified DSN in /etc/odbc.ini and 
$HOME/.odbc.ini, with the latter taking precedence.
"

Do you have a $HOME/.odbc.ini?

Also in odbc.ini, per man odbc.ini, I believe you have to have something 
like:

[ODBC Data Sources]
Postgresql = This is my Postgres DSN.

 From man odbc.ini:

"[ODBC Data Sources] section

	The required section [ODBC Data Sources] lists each data source name 
(DSN) as a key. The associated values serve as comments. Each  entry 
must be matched by an ini file [section] describing the data source.
"

Not following.
 From my experiences with the ODBC driver it is backwards compatible, so 
I would think using a more recent version would be the preferred solution.
