Postgres ODBC woes

Hello,

I am new to postgres and I am having trouble hooking it up to a Microsoft
Access database via ODBC. I am able to CONNECT to the postgres database
server and have both tables appear in the "tables" section of Access. But
once I double click on one of the tables in MIcrosoft Access (which is an
empty table), all I get is a completly blank table where I can't even insert
a record. When I try double clicking on the other table (which has a single
record in it), Access complains "ODBC--call failed" without another
explanation dialogue box following it. I don't know why it would fail like
that.

Here are a few questions:
1) Where are the postgres log files? I see pg_log in /usr/local/pgsql/data,
but it seems to be encrypted or something
2) I notice in /usr/local/pgsql there is a file called "odbcinst.ini". Am I
supposed to alter this file?
3) Where in the Postgres manuals does it describe how to install an ODBC
connection. I can't seem to find it.
