    Have you tried to make a connection?


Tried.

[code]
IgorsGentoo/home/igor/dbhandler_new/Debug #cat /etc/unixODBC/odbcinst.ini
Trace=yes
TraceFile=/tmp/sql.log
[PostgreSQL]
Description=PostgreSQL drver
Driver=/usr/lib64/psqlodbcw.so

IgorsGentoo/home/igor/dbhandler_new/Debug #cat /etc/unixODBC/odbc.ini
[PostgreSQL]
Driver=PostgreSQL
Server=localhost
PORT=5432
DATABASE=draft
OOPTION=3
USER=postgres
PASSWORD=wasqra
IgorsGentoo/home/igor/dbhandler_new/Debug #

igor@IgorsGentoo~/dbhandler/Debug $isql -v PostgreSQL
[IM002][unixODBC][Driver Manager]Data source name not found and no default driver specified
[ISQL]ERROR: Could not SQLConnect
igor@IgorsGentoo~/dbhandler/Debug $

[/code]

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.
"

I'd like to develop backward compatible software which is compatible
with the oldest possible combination..

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.
