I suppose you want something a bit less trivial than this one, but if
somebody has benefit from it, here's the script I've been using to patch
my dbs. It's very trivial - error checking is dba-eyeballs, for example.
But if there are lots of databases, at least it saves a few steps.

A more complete solution would of course require some better error
checking ;-)
