Suppose you are using psql to work with PostgreSQL. In this case, psql
is the PostgreSQL client and PostgreSQL instance is the PostgreSQL
server. So if you deploy Pgpool-II, psql connects to Pgpool-II, and
Pgpool-II connects to PostgreSQL. This is what "Pgpool-II is a
middleware that works between PostgreSQL servers and a PostgreSQL
database client".
