postgres "Returns Table" returns a string

Question

I am using the SQL language on Postgres to return a table using the RETURNS TABLE command:

CREATE OR REPLACE FUNCTION procreadbudget()
  RETURNS TABLE(budgetmonth character, budgetincome numeric, budgetexpense numeric) AS
$BODY$
SELECT budget_month, budget_income, budget_expense FROM budget ORDER BY unique_id;
$BODY$
  LANGUAGE 'sql' VOLATILE

All the data is returned as a comma delimited string, not as a table:

"(Jan,1123,1201)"
"(Feb,1098,996)"
"(Mar,1545,1345)"
"(Apr,1564,1952)"
"(May,1123,990)"
"(Jun,1345,1234)"
"(Jul,1234,878)"
"(Aug,1139,1187)"
"(Sep,1076,1123)"
"(Oct,873,956)"
"(Nov,1298,1423)"
"(Dec,1123,1324)"

Any suggestions please, Mike

Answer 1

do like this:

select t.budgetmont,
       t.budgetincome,
       t.budgetexpense
from procreadbudget() as t

Answer 2

Use

SELECT * FROM procreadbudget();

instead of

SELECT procreadbudget();

Answer 3

Thanks Frank and Tiny, I managed to work this out but there is very little documentation. Coming from MSSQL and MySQL background I was calling the function like a stored proc. Mike5.
