Hi, I found two crashes, actually I found them on the original patch Álvaro sent on november but just checked that those already exists. I configured with: CFLAGS="-ggdb -Og -g3 -fno-omit-frame-pointer" ./configure --prefix=/opt/var/pgdg/15/merge --enable-debug --enable-depend --enable-cassert --with-llvm --enable-tap-tests --with-pgport=54315 And tested on the regression database. Attached the SQL files for the crashes and its respective stacktraces. FWIW, the second crash doesn't appear to be caused by the MERGE patch but I cannot trigger it other way. -- Jaime Casanova Director de Servicios Profesionales SystemGuards - Consultores de PostgreSQL
