Personally, if you are trying to do what I think you are trying to do,
I accomplish it with a 'trick' (aka kludge).

When users open my Access 2000 app I add a record to an Access table
called 'sessions' and keep track of the session_id which is created. 
The postgres records I need id's from have the session id stored in them
at creation with the rest of the data, as well as a timestamp.

so I do the following to get the key value of the record I just

MyNow = Now()

rsData!creation_date = MyNow
rsData!session_id = MySession

then I run a query which asks for the key value of the record with
session_id = MySession and creation_date = MyNow.

Works every time
Lots of luck

So I guess the question still remains, how do you get the last inserted

id from a sequence?

I'm using access 2003 & postgres odbc 8.0.02

select @@IDENTITY seems to be MS Specific and not work with postgres.

calling currval has to be a pass-through query which makes it high 
complicated if at all

How does everyone else do this ?

How does any database maintain referential integrity if this doesn't
