i did read both extensively, but finishing all the steps parallel mode or horizontal partitioning mode doesnot work!
but this is my conf file
backend_hostname, backend_port, backend_weight
here are examples
backend_hostname0 = 'localhost' backend_port0 = 5432 backend_weight0 = 1 backend_data_directory0 = '/mnt/work/database'
backend_hostname1 = 'marc.somehost.com' backend_port1 = 5432 backend_weight1 = 1 backend_data_directory1 = '/mnt/work/database'
this is the problem pgpool-II-2.2.2]$ createdb -p 9999 createdb: could not connect to database postgres: server closed the connection unexpectedly This probably means the server terminated abnormally
before or while processing the request.

can someone show how to setup pgpool 2 in parallel *query* mode ie horizontal partitioning
did you look at http://pgpool.projects.postgresql.org/pgpool-II/doc/tutorial-en.html#parallel ?
I'd pay close attention to the restrictions here, too... http://pgpool.projects.postgresql.org/pgpool-II/doc/pgpool-en.html#restriction
