As for persistent connection with PHP, start from here:

Uhmmm no.
Start here: http://pgpool.projects.postgresql.org/
pg_pconnect tends to have a host of issues.

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.
