Noting that that string is only associated with the public schema,
I tried dumping a DB in which the public schema had been dropped
--- no dice --- and then recreated --- and then it reproduces!
Apparently, a schema that's named "public" but isn't the original
one is confusing something somewhere, but I'm not immediately
seeing where.
