nodeSetOp.c: missing additionalsize for BuildTupleHashTable().

jeff-davis · jeff-davis · commit 32ddfaffd149 · 2025-01-07T14:55:53.000-08:00
Provide additionalsize argument, which can affect the calculations for 'nbuckets'. Also, future work for Hash Aggregation will rely on the correct additionalsize. Discussion: https://postgr.es/m/7530bd8783b1a78d53a3c70383e38d8da0a5ffe5.camel%40j-davis.com
