Why specify an explicit database connection?

I make a simple blog for myself and, reading the PHP manual, found this http://us2.php.net/manual/en/function.pg-query.php

It says

pg_query resource ([resource $ connection], line $ query)

...

Note. Although the connection can be omitted, it is not recommended, because it can be a reason for finding errors in scripts.

Why is it not normal to use the last connection? I never planned to have more than one connection open to a PHP script, since this could cause errors for me?
