You should try the latest version in git (which will soon be released
as 2.18.0). The same_schema check has been overhauled, and now can also
store a copy of a databases state to allow checking the same database
over time to see what has changed. It doesn't check *everything* yet,
but the only things missing are some of the more obscure items such
as custom conversions. It should be pretty easy to add in anything
that is not already covered, even for someone not versed in Perl.

That's not much to worry about. It's a pretty straightforward script,
in that it is very easy to determine if it is working for you or not,
even if some of the tests fail. :)
>> I'm not exactly sure how it does it
check_postgres queries the system catalogs, normalizes some things based
on the version, and creates a Perl object representation of the database.
It then compares that to the same thing from a different database/server,
or to a frozen version of an earlier scan.
