I added it and now my odbc.n look like this:

[code]
igor(at)IgorsGentoo ~/dbhandler/Debug $ cat /etc/unixODBC/odbc.ini
[ODBC Data Sources]
PostgreSQL = This is my Postgres DSN.

[PostgreSQL]
Driver=PostgreSQL
Server=localhost
PORT=5432
DATABASE=draft
OOPTION=3
USER=postgres
PASSWORD=wasqra
igor(at)IgorsGentoo ~/dbhandler/Debug $

[/code]

And there is no .odbc.nii n the ~:

[code]
igor(at)IgorsGentoo ~/dbhandler/Debug $ ls -la ~/.o*
-rw-r--r-- 1 igor igor 0 Mar 1 23:10 /home/igor/.odbc.ini
igor(at)IgorsGentoo ~/dbhandler/Debug $ cat /home/igor/.odbc.ini
igor(at)IgorsGentoo ~/dbhandler/Debug $
[/code]

Apparently the file is created when run "isql -v PostgreSQL".
I will look into that.

Thx.
