I don't really know, but the result looks more like a single field formatted as "ROW-WISE" rather than CSV. The official way to get this result is: SELECT ROW( my_table.* ) FROM my_table; http://www.postgresql.org/docs/9.0/static/sql-expressions.html#SQL-SYNTAX-ROW-CONSTRUCTORS -- Regards, Richard Broersma Jr. Visit the Los Angeles PostgreSQL Users Group (LAPUG) http://pugs.postgresql.org/lapug
