For the upcoming release notes in 14.1 I think we'd do well to document
how to find out if you're affected by this; and if you are, how to fix
it.

I suppose pg_describe_object can be used on the contents of pg_shdepend
to detect it.  I'm less sure what to do to correct it -- delete the
bogus entries and regenerate them with some bulk query?
