It is, but I am told that it is not really very efficient, and so
pg_connect will actually give you better performance on heavy-load
sites. Again, I've heard this but cannot substantiate.

The pool is specifically designed to do just that - manage connections
and keep existing ones maintained - so it is lightweight and fast.
You can get more info here:

I've used it for Oracle-powered sites, as well as putting something
sane between zope/plone and both Oracle and MS SQL.
