Read what you wrote, and rethink...
If you're desperate you can construct a query string with the variable
value embedded as a literal, and then EXECUTE that. This isn't a great
solution since it forces a re-plan on every execution. We've
occasionally debated ways to do it better, but no such improvement will
ever appear in 7.4 ;-)
