hello, I have some code that gets foreign key information from information_schema.referential_constraints. I was puzzled about why it wasn't returning anything for a while, until I read the information_schema.sql file and the documentation carefully: it has a pg_has_role(c.relowner, 'USAGE') in it and the documentation states "The view referential_constraints contains all referential integrity (foreign key) constraints in the current database that belong to a table owned by a currently enabled role".
Fair enough. But then I read the public draft of SQL 2003 and 200n on this view, and it speaks only of "tables in this catalog that are accessible to a given user or role", rather than ownership. the user I was working with most definately had access. it could also read the pg_* system catalog, such that if I copy/paste the view definition without the pg_has_role() line in it (and massage it a bit to remove the CASTs to sql_identifier and character_data) that user got just what I was expecting. so, is that restriction correct?
