Thanks for your reply guys.My aim is to run multiple queries.Will joins come under multiple queries? or it just mean two or more different queries like one select statement and another select statement? Does postgresql itself supports to run multiple queries or we have to use pgpool-II tool?

Do you mean one query being parallelized, or multiple queries running at once?

PostgreSQL provides no capability to parallelize one query into
multiple processes.

Multiple Queries run in parallel automatically
