does parser still parse those comment out lines?

see the little test below:
--------------------8<--------------------------------------
drop function test();
create or replace function test() returns integer as '
begin
-- raise NOTICE ''can't comment out!'';
raise notice ''didn''''t comment out'';
return 1;
end;' language 'plpgsql';

laser_uni=# \i test17.sql
psql:test17.sql:1: ERROR: RemoveFunction: function test() does not exist
psql:test17.sql:4: ERROR: parser: parse error at or near "t" at
character 84
psql:test17.sql:5: ERROR: parser: parse error at or near "raise" at
character 1
psql:test17.sql:6: ERROR: parser: parse error at or near "return" at
character 1
psql:test17.sql:7: WARNING: COMMIT: no transaction in progress
COMMIT
psql:test17.sql:7: ERROR: parser: parse error at or near "' language '"
at character 1
-----------------8<------------------------------------------------------
while change it to:

------------------------8<---------------------------------------------
drop function test();
create or replace function test() returns integer as '
begin
-- raise NOTICE ''cant comment out!'';
raise notice ''didn''''t comment out'';
return 1;
end;' language 'plpgsql';
------------------------8<---------------------------------------------
would be OK, so, the parser still parse those commented lines?
Is it a bug?
