Re: Problem with multiple comments - Mailing list pgadmin-support

Certainly sounds like a very similar problem. If so, the query is
simply buggy - it's just that a pg_upgrade'd environment is *much*
more likely to run into the problem than before.

I only checked the usages of pg_shdescription. The same bug might well
exist with almost all uses of pg_description.
