I hoped to get pl/pgsql finished before 6.4, but since I got
some private trouble and much serious work, I fear to miss
that target too. Haven't had my fingers on PostgreSQL at all
for the last weeks.

But you're right, the rewrite handler still needs work and
since I spent much time to understand the code it would be
wasted time if someone else has to do it.

Let's see if I find some time sometimes :-)
