I've found a million examples of how to set Autovacuum's configuration settings, but can't seem to find how to list the current configuration.
Postgres 9.1 is the version I'm most interested in.
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';
