It's a kludge, but you can successfully use boolean postgres variables in Access.
To link a form with bound check boxes to a postgres table, link to the table with an odbc driver with 'bool as char'
uncheckedand 'true is -1' checked.
To run queries against a postgres table with boolean fields, use a second odbc driver (which will link to the same
tableunder a different name) with 'bool as char' checked and 'true is -1' unchecked, and in the query use "1" and "0"
asthe true and false values (ie, use variable = "1" in place of variable=true).
It's only a slight pain to link with two driver configurations, and is has been working for me without difficulty for
twoyears now.

I'm not sure really, but it might by a problem with a DATE field that receives TIMESTAMP data. Try casting.
Otherwise, avoid BOOLS with a MS Access front-end... Use INT2 instead.
Hope this helps

I'm not at work right now so don't have the exact details available, BUT...
1. I am not using check boxes.
2. When I insert data into the table via PSQL it displays fine in the view itself. The error occurs when I try to
insert. The user does have all the necessary privileges, etc. I have verified that part about 10 times.
3. I have not changed any of the odbc settings (as you mention) from their default values.

I assume you are using check boxes? This has been a
frequently encountered problem for Access users.
I adopted a specific workaround a while ago, then
forgot about the problem. But before I recommend that
workaround, let's make sure that time has not revealed
a better way. What are your driver settings for
"bools as char" and "true is -1"?
