Bug(s) or not?

Hi!

Simple test suite for current CVS:
%initdb ...
%createdb q
%psql q
q=# select * from pg_class limit 1;
SELECT
q=# select * from pg_class limit 2;
server sent data ("D" message) without prior row description ("T" message)
SELECT
q=# select * from pg_class limit 3;
server sent data ("D" message) without prior row description ("T" message)
server sent data ("D" message) without prior row description ("T" message)
SELECT

Why can I select from pg_class? Other system tables are working properly...

And one more:
q=# create table q(i int);
CREATE TABLE
q=# insert into q values (1);
INSERT 17450 1
q=# insert into q values (2);
INSERT 17451 1

q=# select count(*) from q;
count
-------
2
(1 row)

q=# select count(*) from q limit 1;
count
-------
2
(1 row)

q=# select count(*) from q limit 1 offset 1;
count
-------
(0 rows)

q=# select count(*) from q offset 1;
count
-------
(0 rows)

q=# select count(*) from q offset 0;
count
-------
2
(1 row)

I understand that it isn't correct query, but why pgsql do something strange
instead of say 'error'?
