What advantage is there in limiting it to a tiny size? This is a 'payload' after all...an arbitrary data block. Looking at the patch I noticed the payload structure (AsyncQueueEntry) is fixed length and designed to lay into QUEUE_PAGESIZE (set to) BLCKSZ sized pages.
Hmmmm. Looks like the limitation comes from slru. The true payload limit is (8K - struct members) the way this is implemented.
