PHP persistent connections are not really persistent -- or so I've been told.

Anyhow, what was discussed here was pg_query, not pg_connect. You really want
to reduce the number of pg_query() calls in any case; you haven't told us how
many there are yet, but it sounds like there are a lot of them.

This might just be your TCP/IP stack finding out that the rest of the page
isn't likely to come anytime soon, and start sending it out... or something
else. I wouldn't put too much weight on it, it's likely to go away as soon as
you fix the rest of the problem.
