Summary: Unable to obtain list of tables from the datasource

Initial Comment:
Attempting to use Visio 2007 to access postgres databases for link data to shape purposes results in the error "Unable to obtain list of tables from the datasource". I have tried both the ansi and unicode drivers.

Using the reverse-engineer database portion of visio works fine.

This might make it seem like a bug in Visio, however link data to tables works fine with other odbc drivers.

I have watched a packet trace between the postgres server and the PC in question, and verified that the list of tables is in fact returned from postgres to the PC, but apparently it never makes it from the odbc driver to visio or is corrupted somehow.

I have tried both 8.01 and 8.02 drivers.

Here is mylog:

Message:
Ok, with the snapshot it gets the list of tables, however
two new problems:

First, upon trying to reuse an existing connection, it
simply informs me that the connection failed because a
password was not supplied (it never prompts for one, and
when I created the connection I did not allow it to save the
password in the connection file). So, I created a new
connection, and from there:

Second problem: It shows a list of tables and asks me to
click on the one I would like to use, which then results in
an error that it does not exist.

In the postgres log appears this message (ip address altered):

2007-02-12 12:16:15 MST 192.168.1.1(1653)/xxiii%opennms
SELECT :ERROR: relation "public"."ipinterface" does not exist

If I cut'n'paste that into the following in a psql session:

select * from "public"."ipinterface" limit 5;

It works fine. All I can figure is that when the query goes
through the odbc driver the quote marks are literally being
used as part of the table (and schema) name, and causing it
to fail (or perhaps some other problem, but thats my
assumption). I have attached the mylog output.

Could you try the snapshot dll at
http://www.geocities.jp/inocchichichi/psqlodbc/index.html
?
If it also fails, please attach the Mylog output after setting the Mylog option at setup Dialog page 1.
