Are you sure it's 7.4.1? I wasn't aware that was publicly released yet.

It certainly looks like a bug in PG itself, rather than client-related. I'd
agree with your guess that it's somewhere in the query rewriter.

I'm not aware of any particular limits on joins. There's even a genetic
optimiser that kicks in when joins go above a certain number of tables
(default of 12 but configurable in 7.4 iirc?).
