I don't know why either ;) I am using a JDBC based SQL tool to run that - I don't know if that matters. I just tried this script with Postgres 12 beta2 and there I do not get the initial plan with "never executed" (so the same behaviour as everybody else seems to have). If the reason why my initial plan is different than the "analyzed" plan lies in the configuration, I am happy to share my postgresql.conf if that is of any interest. Thomas
