Hi all, apologize if this is a trivial question but I'd like to understand what values are stored in the RelOptInfo->reltargetlist or, better, how I can check such values in the information schema to understand what they refer to. I've tried to look in the pg_attribute table but I was not able to find a match. In other words, how can I check what is the oid of the listcell pointing to in the database schema?
