Tom Lane 4025e6c466 Do not return NULL for error cases in satisfies_hash_partition(). ... Since this function is used as a CHECK constraint condition, returning NULL is tantamount to returning TRUE, which would have the effect of letting in a row that doesn't satisfy the hash condition. Admittedly, the cases for which this is done should be unreachable in practice, but that doesn't make it any less a bad idea. It also seems like a dartboard was used to decide which error cases should throw errors as opposed to returning NULL. For the checks for NULL input values, I just switched it to returning false. There's some argument that an error would be better; but the case really should be can't-happen in a generated hash constraint, so it's likely not worth more code for. For the parent-relation-open-failure case, it seems like we might as well let relation_open throw an error, instead of having an impossible-to-diagnose constraint failure. Back-patch to v11 where this code came in. Discussion: https://postgr.es/m/24067.1605134819@sss.pgh.pa.us		5 years ago
