pg 7.4.1

I should have listed the source for the function. Here is a simplified
parseString function and the foo that calls it.

dennis=# create or replace function parseString (varchar, varchar)
dennis-# RETURNS varchar[] AS '
dennis'# DECLARE
dennis'# pParsed varchar[];
dennis'# pString ALIAS FOR $1;
dennis'# pSeparator ALIAS FOR $2;
dennis'# begin
dennis'#
dennis'# -- example simplified
dennis'# pParsed[1] = ''blah'';
dennis'# pParsed[2] = ''hrmmph'';
dennis'#
dennis'# return pParsed;
dennis'# END;
dennis'# ' language plpgsql;
CREATE FUNCTION
dennis=#
dennis=# create or replace function foo() returns varchar as '
dennis'# declare
dennis'# results varchar[];
dennis'# tmpv varchar;
dennis'# begin
dennis'# results := parseString(''asdf'',''asdf'');
dennis'# tmpv := results[1];
dennis'# RAISE NOTICE '' tmpv = % '',tmpv;
dennis'# return tmpv;
dennis'# end' language plpgsql;
CREATE FUNCTION
dennis=# select foo();
NOTICE: tmpv = <NULL>
foo
