That's a good question. The following query does this in a very
unsatisfactory way. Anyone know what the general solution would be?
SELECT pg_namespace.nspname, pg_class.relname,pg_attribute.attname FROM pg_class
JOIN pg_namespace ON pg_namespace.oid=pg_class.relnamespace AND pg_namespace.nspname NOT LIKE 'pg_%'
JOIN pg_attribute ON pg_attribute.attrelid=pg_class.oid AND pg_attribute.attisdropped='f'
JOIN pg_index ON pg_index.indrelid=pg_class.oid AND pg_index.indisprimary='t' AND (
pg_index.indkey[0]=pg_attribute.attnumOR pg_index.indkey[1]=pg_attribute.attnum OR
pg_index.indkey[2]=pg_attribute.attnumOR pg_index.indkey[3]=pg_attribute.attnum OR
pg_index.indkey[4]=pg_attribute.attnumOR pg_index.indkey[5]=pg_attribute.attnum OR
pg_index.indkey[6]=pg_attribute.attnumOR pg_index.indkey[7]=pg_attribute.attnum OR
pg_index.indkey[8]=pg_attribute.attnumOR pg_index.indkey[9]=pg_attribute.attnum )
ORDER BY pg_namespace.nspname, pg_class.relname,pg_attribute.attname;
