I doubt it. PostgreSQL has a higher connection startup overhead than
MySQL, so if every view required a new database connection, it would been
quite a detriment to the PostgreSQL scores.
PHP can maintain persisitant connections. Unfortunately, this means
that you end up with a database connection per httpd process. That really
isn't a problem for PostgreSQL though, it just requires sufficent memory.
No doubt that is what was being done.
AOLServer isn't the only system that can pool database connections, so
can servlets/JSP, ColdFusion, ASP, etc. No doubt AOLServer would be more
widely accepted if it used something other than TCL.
