That's a bit disturbing --- do you have any idea what triggered that?

I'd do the latter I think. Keep in mind that there are probably also
entries in pg_depend linking the tables to the schemas. If your goal is
only to get to a clean dumpable state and then dump and reload the
database, you probably don't need to worry about fixing pg_depend.
However, if you intend to keep on using the database without a reload,
it'd be prudent to make sure pg_depend is straightened out as well.
