Best Practice to Create a Connection Pool in PostgreSQL

Hi,

I’ve been looking through the mail archives in the JDBC forum and have seen a number of different ways to create a JDBC connection pool to Postgres.  Could someone point me in the right direction, eg Jdbc3ConnectionPool, Apache's DBCP, etc.?

I’m using the following:

JRE:                             1.6

PostgreSQL Server:      8.3

JDBC Driver:                 postgresql-8.2-506.jdbc4

Thanks.
