Обсуждение: Re: Cannot link to postgres 8.0.0 databases using ODBC from

Further investigation of the problem I described in my previous posting has
identified a fault that I suppose is applicable to the combination of
Postgres 8.0.0 ODBC driver running on Windows 2000 server and desktop.

I have two postgresql.conf files, one is the default out-of-the-box
postgresql.conf file, the other has many of the logging options turned on
(I have put the diff between the two files at the end)

The default config works fine, the modified config fails in that the
postgres ODBC does not work (tested with Access 97,2000 and Perl ODBC
connections) giving the error "The database does not exist on the server or
user authentication failed. (#105)".

Only ODBC seems to be affected. All other connections from php, pgadmin
work fine.

I have demonstrated this problem consistently on two completely different
and brand new installations of P8.0.0 (W2K server and desktop). I have not
been able to pin down exactly what combination of settings generates the
error.

Regards
Laurie


The diff of the two config files is

Laurie,
    I'm thinking these lines in the log may be of interest:

[unknown] [unknown]  2005-02-17 18:55:59 4214e8bf.9dc 0LOCATION:
BackendRun, postmaster.c:2656

and

ldb rjl_pilot 10.35.10.248(4630) 2005-02-17 18:55:59 4214e8bf.9dc
0LOCATION:  log_disconnections, postgres.c:3403

I'd try turning off log_discconnections, and see if you get any joy.  If
that works and the log still displays problems
related to BackendRun, I'd email the pg-hackers list.
