Another view? Don't you think you've left out a lot of information that
would be needed for anyone trying to reproduce this failure? Please
show the *full* definition of all tables and views involved.
And, as already noted, "8.2" isn't enough information about which
PG version you're running.
If it's an early 8.2.x release and the other view involves any outer
joins, then I could believe that this is explained by one of the outer
join planning bugs we've already fixed ... but without any details
that's only a wild guess.
