Pool of connections

Hi.

What is the best way to make connections to pgsql from PHP?

Today I use pg_connect but I dislike having username and password written in
plain text in my source. Besides, I would like to be able to limit the
number of simultaneous connections to pgsql.

Any hint will be apreciated.

TIA,
