I am returning one value (text). Each of the selects in the function
should also return only one value.

I have seen other functions (written by others) that do this. So I
assume its ok. I'm open to suggestions though. As long as it works.

I'm not certain about this, but is it a mistake to mix OUT parameters
and RETURNS?

I have used OUT combined with "returns setof record", it makes the
result set have the columns specified as OUT params.
like:
create or replace function TotalCustProd( xsdate timestamp, xedate timestamp,
out xcust varchar(100), out xcontract varchar(80), out xjob text,
out xtask text, out xparcels integer,
out xhours float, out xrate float, out xpclperhour varchar(1),
out xamount float
) RETURNS SETOF record AS $$
the result set would be xcust, xcontract, etc...
Newer versions of PG have "returns table" support:
create or replace function findBadRates(sdate date) returns
table(rrowid integer, rlookuprate decimal(5,2)) as $$
Do you want to return one single value, or a set of rows?
