I cannot readily reproduce this. Which version of Postgres is this and on which platform/distribution? Did you try keep jit on but set jit_inline_above_cost to 0? The back-branches have a fix for the above case, i.e. llvmjit memleaks that can be worked-around by setting jit_inline_above_cost=0. Michael
