Correct, seems to be something wrong on system tables. Maybe our script is running something is already there, we will check. select * from pg_stat_sys_tables where schemaname = 'pg_catalog' relname n_live_tup n_dead_tup pg_attrdef 3699 1095 pg_index 4756 1183 pg_sequence 20827 1482 pg_statistic 171699 27101 pg_trigger 221319 20718 pg_shdepend 225017 22337 pg_attribute 883023 164153 pg_depend 1553586 142960 and all them last_vacuum is null and last_autovacuum is too old. So, is it better to configure autovacuum properly to these tables or should I run vacuum periodically ? Obviously I´ll check our script too. -- Sent from: https://www.postgresql-archive.org/PostgreSQL-general-f1843780.html
