Looking up Postgres table name by id

Mon, 24 Oct 2016 00:00:00 +0000

When working with [TOAST][1] tables, I had the relid (relation or table id) of the parent table, and needed to get its name.

Here is how to perform the lookup. For example, if the relid is 19665:

SELECT relid, relname FROM pg_catalog.pg_statio_user_tables WHERE relid = '19665';
