Mysterious column "name"

Good day!

I found one strange results for sql-query.

create table testtable (
f1 int,
f2 int
);

insert into testtable(f1, f2) values(1, 100);

select testtable.* from testtable; // it is ok

select testtable from testtable; // it is ok

select testtable.name from testtable; // returns strange result.
-----------------------------------------------------------------
name
name
-----------------------------------------------------------------
"(1,100)"
-----------------------------------------------------------------
no error message about nonexistent column.
Result is similar to second variant, but pgAdmin3 shows not full record.

for long table the result is truncated
select aaaaaa."name"
from yc_accounts aaaaaa
-----------------------------------------------------------------
name
name
-----------------------------------------------------------------
"(1154,81,testtter,"","","","","","","","","",donald22@126.com,""
-----------------------------------------------------------------

The same results on two servers.

Is it a feature or a bug? I didn't found information in documentation 
about this.


Best regards.
