nextval result type difference between 7.1.3 and 7.2.1

Hello,

I use PostgreSQL, UnixODBC, and Lisp configuration.

I call 'nextval' to get an ID on Lisp like:

        (query "select nextval('UNIQUE_ID_SEQUENCE')")

With PostgreSQL 7.1.3 and UnixODBC 2.0.7 or 2.2.3 it returns an
integer(ex, 123), but with PostgreSQL 7.2.1, it returns a string(ex,
"123").

Any idea how to fix the problem?

Cheers,

- Jong-won Choi

nextval returns bigint (int8) in 7.2 and later.

You can cast the result down to integer in your query, or you can
figure out why ODBC isn't coping ... I have a vague recollection
that this may be an ODBC configuration issue ...
