Excuse me,

I'm new for pgpool-II, finally I was able to properly configure pgpool in order to perform a parallel query.

But, here comes a trouble for me, I build my cluster in parallel mode, following the tutorial

I using commend of
/usr/pgsql-9.1/bin/pgbench -i -s 3 -h -p 9999 -U postgres bench_parallel
to insert test data to pgpool, and it looks 3 backend postgre node is having the right data inserted.

but when i running commend of 
[root at zhengpengfei ~]# psql -h -p 9999 -c "select BID,COUNT(*),MIN(aid),MAX(AID) from pgbench_accounts GROUP BY BID" bench_parallel -U postgres
ERROR:  could not establish connection
DETAIL:  could not translate host name "devserver3" to address: Name or service not known

my pgpool node ip is
which hostmane is devserver3

what's the problem?

thanks at first and best regards
