Re: Toast table get list from instance

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.
