OpenLayers runs in your browser and it can not work "DIRECTLY" with 
postgres/postgis but is can work via a simple Ajax request to a PHP or 
other service you provide on the server.

There are plenty of examples and probably a tutorial:
http://www.google.com/#hl=en&source=hp&q=pgrouting+openlayers

Since pgRouting runs in the database and PHP can trivially access the 
database, it is very straight forward to write a simple PHP routing that 
  takes a starting and end location via an Ajax request, then makes the 
appropriate SQL queries to the database and gets back its results that 
are then returned to the browser is simple XML. In Javascript you parse 
the XML, there are tools to help already in OpenLayers, and display the 
track as a vector layer.

Here is a demo I put together. However it uses code that is not part of 
pgRouting, but the idea would be the same for what you are trying to do.
