Only query and reproduction make sense for me to discover more deeply at the moment. It looks like we have managed to reproduce the potential 'Hash over parameterised subtree' issue. Please check the attachment: there are two plans. One plan has a longer execution time and more blocks hit, but its cost estimate is four times lower. The EXPLAIN output does not show any obvious estimation errors. This suggests there may be a bug in the cost model. -- regards, Andrei Lepikhov, pgEdge
