In fact an even more useful option would be to ask the planner to throw

Well, I've suggested it before:
statement_cost_limit on pgsql-hackers, 1 March 2006

Would people like me to re-write and resubmit this patch for 8.4?

Tom's previous concerns were along the lines of "How would know what to
set it to?", given that the planner costs are mostly arbitrary numbers.

Any bright ideas, or is it we want it and we don't care about the
possible difficulties?


Knowing how to set it is a problem - but a possibly bigger one is that monster query crippling your DW system, so I'd say lets have it.

Cheers
