Table Functions
- PL/PgSQL and C functions can now return sets, with multiple
- rows and multiple columns. You specify these functions in the
- SELECT FROM clause, similar to a table or view.
+ Functions returning multiple rows and/or multiple columns are
+ now much easier to use than before. You can call such a
+ "table function" in the SELECT FROM clause, treating its output
+ like a table. Also, plpgsql functions can now return sets.
