Description: unlogged table with Streaming Replication
Details:

Hi,

I've checked "unlogged table" and "Streaming Replication".
I'm thinking about using unlogged tables as work-tables on Primary.

1) construct Streaming Replication Environment.
Primary and Standby are same server with different database cluster and
port number.

2) create unlogged table on Primary.
=# CREATE UNLOGGED TABLE tbl1(i int);
This table is available on primary only.

3) Stop Standby.
[standby]$ pg_ctl stop

4) create unlogged table on Primary again.
=# CREATE UNLOGGED TABLE tbl2(i int);

when I executed 4), any response is not back to my psql. and I canceled the
query, I got messages bellow.
---
Cancel request sent
WARNING: canceling wait for synchronous replication due to user request
DETAIL: The transaction has already committed locally, but may not have
been replicated to the standby.
CREATE TABLE
---
and the table has been created.

I think It's strange behavior(a canceled table has been created).

Is this the same problem with "BUG #6041"?
