D'oh! My lysdexia must've kicked in. I saw "no InnoDB".

I was just amused that it appeared to say that it's preferred 
relational database was not, erm, relational. Again, I misread.

Agreed. That's why I use Mail (for now).

Yes, I know.

I haven't tried the triggers yet.

I tried them, but their magic auto-updateness didn't work for any but 
the simplest examples. But it's early yet. I'll look again when they're 
a little closer to release.

No, I mean RULEs, which are slightly different to but similar to 
triggers. In PostgreSQL, you attach rules to views so that you can 
execute update, insert, and deletes against them. SQLite does the same 
thing but uses triggers.

About time. I don't see a version number reference there, though. But 
5.0 is shaping up to be an interesting release. I look forward to 
seeing it late next year.
