Per my point #2, that would be the wrong solution, quite aside from the
wrongness of dumping the fixup burden on the extension author. For one
thing, the extension author has no idea whether his script is being
loaded into a database that has this patch. If it doesn't, adding a
command like this would cause the script to fail outright. If it does,
then the command is unnecessary, since the patch also includes a code
change that adds the dependency.
But in any case, making rules act differently from other table
properties for this purpose seems seriously wrong.
