Oh: then you're doing it wrong. If you want to remember that WITH
SCHEMA was specified, you need to explicitly store that as another
column in pg_extension. You should not be depending on the dependency
mechanism to remember that for you, any more than we'd use pg_depend to
remember a table's relnamespace. The dependency mechanism is there
to figure out the consequences of a DROP command, it's not there to
remember arbitrary facts. (And yes, I know that we've cheated on that
principle a few times before; but you can't do it here.)
