Looking at this issue today, I found that we are not setting a
dependency for an index created inside an extension. I don't know if
it's deliberate or an overlook.

The thing is that we can't check pg_depend for dependency of an index
and the extension that creates it.

I was talking with other developers, and we kind of agree this is a
bug, for 2 reasons we thought of:

*) If the extension only creates an index over an existing table, a
drop extension will not drop that index

*) We need to have the dependency for this patch as well, else we'll
end up with an inconsistent dump, or at least one that could restore
with a != 0 return error code.

I'll open a separate bug report for this.
