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.
