RE: [HACKERS] MAX Query length

Well, I'm starting on this, so hopefully in a couple of weeks the length
limit of the query buffer will fade into insignificance.
Is somebody actively working on removing the tuple-length dependence on the
block size?

At present, disk blocks are set to 8k. Is it as easy as just adjusting the
constant to enlarge this? Testing queries larger than 16k with only an 8k
tuple size could be challenging.
