select *
from pg_settings 
where name like 'autovacuum%'

对于表特定设置,请查看pg_class中的列重定位：

select relname,reloptions
from pg_class

您可能希望将其加入pg_namespace以将其限制为特定架构.需要在隐藏的col pg_namespace.oid上添加连接(添加9.3).

select relname,reloptions,pg_namespace.nspname
from pg_class
join pg_namespace on pg_namespace.oid = pg_class.relnamespace
where relname like 'data%' and pg_namespace.nspname = 'public';
