Sure it's dumpable.  The point here is that name_pattern_ops is a
built-in object and so pg_dump doesn't think it should dump it.
Changing its name doesn't make it not built in.

I think you're going to need to draw a distinction between built-in and
not-built-in configurations.  The canonical way to do this is to put
them into schemas and say the ones in pg_catalog are built in.  And yes,
you need to ensure that there's not a good reason for people to change
the built-in ones.
