did you see http://pgpool.projects.postgresql.org/pgpool-II/doc/pgpool-en.html#master_slave_mode
? I think it answers your question :-)

warning:
it works by detecting which queries are read-only, which does not
always work "out of the box".
you will sometimes have to modify driver settings or worse, modify SQL
queries including "hints" for pgpool.

see:
