I know they are stored in one of the system tables, but > I don't know which. - Table names are in pg_class - Column names are in pg_attribute, associated to pg_class via "where pg_attribute.attrelid = pg_class.oid" - Comments are in pg_description... There seem to be links to both pg_class and pg_attribute - Type info is in pg_type, associated to pg_attribute via "atttypid" There are attributes that you normally don't see, and "dropped" attributes still exist in pg_attribute, so things are a tad more complex than what I have said, but the above 4 tables should provide you all you need... -- select 'cbbrowne' || '@' || 'acm.org'; http://linuxdatabases.info/info/slony.html Never criticize anybody until you have walked a mile in their shoes, because by that time you will be a mile away and have their shoes. -- email sig, Brian Servis
