As for persistent connection with PHP, start from here: http://php.net/pg_pconnect. Also, I recommend to ensure that you have proper set of indexes on your tables and your system doesn't use badly written queries (such as join of several dozens of tables :-) ). There is an excellent tool that can help you monitoring your database, pgFouine: http://pgfouine.projects.postgresql.org/. I recommend it highly, it really helps to understand what queries are "bottle neck" of your system and when (the time of the day) the load reaches maximum. Good luck.
