Recently，i meet a problem about autovacuum
this option "autovacuum: ANALYZE pg_catalog.pg_attribute" has lasted for a long time, and the process, "postgres :autovacuum worker process ngfw_log" is using a high cpu. this problem is only found in this table——“pg_attribute”，what‘s the problem and how can i solve it or research ?
this is my configure
and the gdb bt result
looking forward to your reply .
thanks!
