How to view the current settings of Autovacuum in Postgres?
For the general settings use:

select *
from pg_settings 
where name like '%autovacuum%'


for table specific settings, check out the column reloptions in pg_class:

select relname, reloptions
from pg_class


You will probably want to join that to pg_namespace to limit this to a specific schema. Where joining needs to happen on the hidden col pg_namespace.oid (added 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';
