Re: [GENERAL] pg_relation_size, relation does not exist

The same problem, missing oid's, occurs with several other system views as well. If you have to do some serious work, it's always pg_class you need. oid's in these views would be nice, but only if all the system views have the oid's of the underlaying objects. In case of pg_tables you nee

Actually, is there any particular reason why we can't *add* that column to the view in a future version? We certainly shouldn't go modify it, but adding to it should be pretty safe, no? -- Magnus Hagander Self: http://www.hagander.net/ Work: http://www.redpill-linpro.com/ Frank Heikens wrote

The search_path isn't correct. You're looking for the size of tables in schema 'econ' but you don't mention this schema inside the function pg_relation_size(). Try to use the schemanames as well, saves you a lot of problems with assumptions. This one should work: SELECT tablename,
