Did not take long... [pryzbyj@database ~]$ while :; do for db in `psql postgres -Atc "SELECT datname FROM pg_database WHERE datallowconn"`; do for t in pg_statistic pg_attrdef pg_constraint; do echo "$db.$t..."; PGOPTIONS=-cstatement_timeout='9s' psql $db -qc "VACUUM FULL $t"; done; done; done ... postgres.pg_statistic... postgres.pg_attrdef... postgres.pg_constraint... template1.pg_statistic... template1.pg_attrdef... template1.pg_constraint... ts.pg_statistic... ERROR: canceling statement due to statement timeout ts.pg_attrdef... ts.pg_constraint... postgres.pg_statistic... ERROR: missing chunk number 0 for toast value 3372855171 in pg_toast_2619 I'm running this again on another DB, but I wonder if that's enough for anyone else to reproduce it with some consistency ? I think that took something like 10min before failing. Justin
