Forgot to say how postgres was started. Via my usual devenv script, which results in: + /home/andres/build/postgres/dev-assert/vpath/src/backend/postgres -c hba_file=/home/andres/tmp/pgdev/pg_hba.conf -D /srv/dev/pgdev-dev/ -p 5440 -c shared_buffers=2GB -c wal_level=hot_standby -c max_wal_senders=10 -c track_io_timing=on -c restart_after_crash=false -c max_prepared_transactions=20 -c log_checkpoints=on -c min_wal_size=48MB -c max_wal_size=150GB -c 'cluster_name=dev assert' -c ssl_cert_file=/home/andres/tmp/pgdev/ssl-cert-snakeoil.pem -c ssl_key_file=/home/andres/tmp/pgdev/ssl-cert-snakeoil.key -c 'log_line_prefix=%m [%p][%b][%v:%x][%a] ' -c shared_buffers=16MB -c log_min_messages=debug1 -c log_connections=on -c allow_in_place_tablespaces=1 -c log_autovacuum_min_duration=0 -c log_lock_waits=true -c autovacuum_naptime=10s -c fsync=off Greetings, Andres Freund
