I have slight problem on a postgresql-server-8.1.11-1PGDG.rhel4 db.
The first statement below runs fine. But the second two statements
return no results. When these statement are not run as prepared
statements they work fine. I need to run them as a prepared statement
because of the parameterization, but I don't want the server to cache
the prepared nature of the statements. These statements worked fine on
an old 7.3 driver. The only differendce I could see was that the driver
didn't prepare them.
