The rule plan is stored as a tuple, hence for this release that limit
is a little under 8k.

For 6.4, you will be able to use a bigger block size, therefore have
bigger tuples and this should then work again.

Sounds like the plan internally grew (possible w/subselect stuff?!?) and
has gone over that 8k limit.

I know it's little consolation, but as soon as I can get the variable
block size working (actually only breaks in the create_triggers regression
test when sorting to disk), I could post it as a patch for 6.3 as well as
put it into the 6.4 tree.
