I can see that would be useful.

I have no objection to extending the capabilities in general.

However, I'm really not keen on this idea for a couple of reasons:
1) We used to include the PostgreSQL documentation with pgAdmin, and
it was a *real* pain to maintain. We got rid of it because it was so
burdensome, and because virtually everyone works online now anyway.
2) Building the PG docs on Windows is nigh-on impossible. Including
the feature you suggest would make it near impossible to build pgAdmin
on Windows - at best it would probably require building the docs on a
Linux system first, which is not acceptable.

Aside from the issues above, we already have search capabilities in
Sphinx (though, I haven't spent time playing with them yet).
I wonder if an alternate approach to this problem would be to have a
web service on one of our machines that can create the keyword index
of the PostgreSQL docs, that can be downloaded and cached for use by
pgAdmin, or other apps.
