I just tried using pg_pconnect() and I didn't notice any significant
improvement.  What bothers me most is that with Postgres I tend to see jerky
behavior on almost every page:  the upper 1/2 or 2/3 of the page is displayed
first and you can see a blank bottom (or you can see a half-filled completion
bar).  With MySQL each page is generally displayed in one swoop.
