You can use the following query to get the info from one database.
SELECT
nspname AS schema_name,
c.relname AS toast_table_name,
c.oid AS toast_table_oid,
r.relname AS main_table_name
FROM
pg_class c
JOIN
pg_namespace n ON n.oid = c.relnamespace
LEFT JOIN
pg_class r ON r.reltoastrelid = c.oid
WHERE
c.relkind = 't';
But to get info from all the databases then you need to write a shell script which will first get all the databases and then run the above query on the all returned databases.
