Assuming you mean a DBI database handle, then funnily enough it has
something almost exactly like that. Check out "ATTRIBUTES COMMON TO ALL
HANDLES" in 'perldoc DBI'. Also see the ping function in "Database
Handle Methods".
The DBI documentation is fairly large, but it is searchable. Also, if
you are going to use the DBI module in earnest, I would recommend
getting the book "Programming the Perl DBI".

They used to produce the documentation in that format, but it was
difficult (if not impossible?) to update when a module was installed or
upgraded, because to do so required proprietary software. Also, it is
kind of platform specific, and html isn't.

Understandable if that is what you are used to, but Perl comes from a
different world. The majority of Perl documentation is in POD format,
which is converted to a fairly good html form by Activestate. Personally
I find a combination of that and the command line tool (perldoc) to give
me most of what I need. Some people, like $Bill (if you ask nicely he
may be tell you how) collect all of the documentation into a single file
which they find easier to search.
If you want to generate documentation in chm format yourself, it should
be possible. If my internet connection was working better I might be
able to give a pointer or two, but I would suggest starting at
http://search.cpan.org/.
