Postgres pg_toast in autovacuum - which table?
Here's a shorter way:
select 15404513::regclass;
where 15404513
is pg_toast_
suffix.
I think you'll want something like:
select n.nspname, c.relname from pg_class c inner join pg_namespace n on c.relnamespace = n.oidwhere 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') )
It'd be nice if Pg reported this in the vacuum command summary.
