### Is your feature request related to a problem or challenge? #25790 added interval analysis to estimate filter selectivity on Decimal columns. On TPC-H Q18 this change made the plan use a much worse join order: the query took about 233 s and 22 GB of peak memory, compared with about 7 s and 4 GB before (#27108). #27145 reverts the change for the 56 release. ### Describe the solution you'd like Find out why the new estimate changes the Q18 join order. Then re-land #25790 with a TPC-H Q18 plan check, so that this regression cannot return. cc @shrivasshankar @devanbenz -- This is an automated message from the Apache Git Service.
