It just passes the whole connection string through to the PostgreSQL
library libpq. So it isn't a problem with PHP. I tried it and it works for
me. I added "connect_timeout=2" to my connection string, and I got this
error (in 2 seconds) when trying to connect to an invalid IP address:

  Warning: pg_connect() [function.pg-connect.html]: Unable to connect to
  PostgreSQL server: timeout expired . in ...

I had to use 2 seconds. With 3 seconds or longer, I get a "no route to host,
is the server running..." error before it times out.

I'm running PostgreSQL-7.4.1 and  PHP-4.3.3 on Slackware 9.1 Linux. If the
problem you are having is fixed by an upgrade, I would try PostgreSQL-7.4.1
first (because I don't think PHP will affect it).
