info is a reserved word?

I have two identical functions below, the only difference is I
declared my variable name to be 'info' instead of 'stuff'. I could
not find anywhere in the docs that 'info' has any special meaning.
Did I miss it?

create type my_info as (
a text,
b text
);

-- this works
create or replace function my_stuff ()
returns my_info as $$
declare
stuff my_info;
begin
stuff.a := 'hi';
stuff.b := 'there';
return stuff;
end;
$$ language plpgsql;

create or replace function my_stuff ()
returns my_info as $$
declare
info my_info;
begin
info.a := 'hi';
info.b := 'there';
return info;
end;
$$ language plpgsql;

Evaluating this definition gives:

psql:16: ERROR: syntax error at or near "info" at character 71
psql:16: LINE 4: info my_info;
psql:16: ^
