Hi Andrew,
Bingo, set enable_parallel_hash=false; gets a correct result whereas set enable_parallel_hash=true; gets 0.
Yes I might have reversed some of the explains, my excuse its Friday and I went to bed late and am burnt out today :-)

This is looking like a bug in parallel hash. Do the queries all work if
you do set enable_parallel_hash=false; ?
(Going by the row counts in the explains, you got the first two "broken"
and "working" ones backwards)
