It implements preparable statements, by adding 3 new SQL statements:

PREPARE <plan> AS <query>;
EXECUTE <plan> USING <parameters>;
DEALLOCATE <plan>;

I didn't write the original patch -- that was done by Karel Zak.
But since that was several years ago, I'm working on cleaning it up,
getting it to apply to current sources (which has taken a while),
and fixing the remaining issues with it. Karel describes his work
here:

http://groups.google.com/groups?q=query+cache+plan&hl=en&selm=8l4jua%242fo0%241%40FreeBSD.csie.NCTU.edu.tw&rnum=1

(If that's messed up due to newlines, search for "query cache plan"
on Google Groups, it's the first result)

Cheers,

Neil
