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.
