Обсуждение: Finding filenames for tables
I must be having a bad search-engine day. How do I join pg_class and pg_database to determine OID/tablename pairs for a given database? I can't find anything to join on in those tables. I'm just grepping output right now, but I'd like to do more complicated things in the future, thus my question. -j -- Jamie Lawrence jal@jal.org

You cannot see any classes from a different database in pg_class. In contrast, pg_database is server-wide mirrored. Regards, Andreas
