Works for me:

regression=# create function foo() returns int as '
regression'# declare f_count_var integer;
regression'# begin
regression'# select into f_count_var count(unique1) from tenk1;
regression'# return f_count_var;
regression'# end' language plpgsql;
CREATE FUNCTION
regression=# select foo(); foo
-------10000
(1 row)


What PG version are you using?
        regards, tom lane

try:
f_count_var := count(empno) from employee;
