It was as a reply to your post last year:

Maybe I should've voiced my opinion more strongly back then..

I'd just like to keep the core JDBC driver slim as a matter of
principle. Given that most application servers already have their own
connection pooling and prepared statement caching implementation, and
the fact that there's other stand-alone implementations out there
(Apache DBCP, for example), most people who need the JDBC driver don't
need another connection pool and statement cache.

As a separate module, the pool and the cache could get a wider audience.
You could use it with different databases and JDBC drivers in addition
to PostgreSQL. And it wouldn't be tied to PostgreSQL driver release
cycle, and vice versa.
