When calculating distance in brin_minmax_multi_distance_inet(), the netmask was applied incorrectly. This results in (seemingly) incorrect ordering of values, triggering an assert. For builds without asserts this is mostly harmless - we may merge other ranges, possibly resulting in slightly less efficient index. But it's still correct and the greedy algorithm doesn't guarantee optimality anyway. Backpatch to 14, where minmax-multi indexes were introduced. Reported by Dmitry Dolgov, investigation and fix by me. Reported-by: Dmitry Dolgov Backpatch-through: 14 Discussion: https://postgr.es/m/17774-c6f3e36dd4471e67@postgresql.org |
