No. Can you show us an example?

test=*# select * from o;
i
---
3
1
2
(3 rows)

test=*# create or replace function my_count() returns int as $$declare c int;begin select into c count(1) from o where i=2; return c; end;$$language plpgsql;
CREATE FUNCTION
test=*# select * from my_count();
my_count
----------
1
(1 row)

In other words: works for me.
