我有一个在pg_toast上运行的autovacuum进程：
@H_403_1@select query,from pg_stat_activity where query like '%autov%';
"autovacuum: VACUUM pg_toast.pg_toast_15404513 "
我如何找到什么表/索引/这pg_toast属于什么？还是自动真空工作在别的什么？
我想你会想要这样的东西：
@H_403_1@select n.nspname,c.relname
from pg_class c
inner join pg_namespace n on c.relnamespace = n.oid
where reltoastrelid = (
select oid
from pg_class
where relname = 'pg_toast_15404513'
and relnamespace = (SELECT n2.oid FROM pg_namespace n2 WHERE n2.nspname = 'pg_toast') )
