Here's what I get on Ubuntu 12.10. The bug is likely to be
Windows-specific. Whether it is a bug in Windows or in PostgreSQL
character-handling under Windows I can say myself, since I haven't

test=# create or replace function α(β int, ξ int, μ float) returns float as $$
select (β + ξ) * μ $$ language sql;
CREATE FUNCTION
test=# \df+
