There was something awfully fishy about that.  Brian was saying that he
got a seqscan plan out of "WHERE foo = 100", where foo is an integer
primary key.  That's just not real credible, at least not once you get
past the couple of standard issues that were mentioned in the thread.
And we never did get word one of information about his join problems.

I suspect he'd made up his mind already.  Which is his privilege, but
it'd be nice to have some clue what the problem was ...
