Example is in attachments.

I try this example:
a) works wrong on pg 7.1.3 on SUSE Linux 7.0 (SELECT version() =>
PostgreSQL 7.1.3 on i686-pc-linux-gnu,compiled by GCC 2.95.2)
b) works OK!!! on pg 7.1.2 on Debian Linux 2.2.19 potato (SELECT
version() => PostgreSQL on i686-pc-linux-gnu,compiled by GCC 2.95.2)
c) works wrong on pg 7.1.3 on Debian Linux 2.2.20 potato (SELECT
version() => PostgreSQL on i686-pc-linux-gnu,compiled by GCC 2.95.2)

I don't uderstand (why this example works on Pg 7.1.2 and on Pg 7.1.3
not works)!
Error is in configure param?

Thanks

PS: sorry form my english
