Right, and wrong. TOAST will solve this, and it will be ready for 7.1. It's
in the current sources, BTW (I'm developing an app which uses it and I
haven't had any problems working with Postgres from CVS).
I've heard that people sometimes run into problems setting BLCKSZ to
32K - I'd suggest staying under 30K.
BTW, although most emails are < 8K, some could be > 1 meg (attachments,
deliberate attempts to cause problems). So increasing BLCKSZ isn't
the only thing you can do. Perhaps the best solution would be to
determine BLCKSZ at runtime (possible?), and then either reject
stuff > than that, or store it as a LO.
