yes, all is local here.

to be honest, I'm not sure... I just used the port-number that was used in the
documentation (the example), assuming it is correct. ;-)
I did'nt checked the port-number...

well.... is this necessary?
I just used the examples, and all that is different, I changed.
If the examples are missing the user/passwd, then I also did not used it.
BTW: here did you miss it? In /etc/odbc.ini?

Van you explain me the "???" and the READDBID / READDBUSER / READDBPWD ?!
Looks like env-vars included here in the configs?!

With psql I can connect.
Was this your question?
Or do you mean other tools?
