I create an ASP.Net web page which I want to incorporate in my Site
definition (in this case the SPS) site definition.

You can see pages like search.aspx and others but I want to make my
own search.aspx (MySearch.aspx)

If I add the page on this place and create a new site, it
automatically creates a record in the database to the new page (an
entry in the Docs table).

But the problem I have is that the page is not available for existing
sites.

I was thinking to call the stored procedure to add the "ghosted" page
to my existing sites: proc_AddDocument.

Before calling this stored procedure, and cause a huge problem on my
sites, I want to know if somebody wants to share the experience
resolving a similar issue like this....
