Is it possible that you've got tables lying around that have ordinary-
circle-type fields in them?  Vacuum analyze would notice the lack of
type data, but I'm not sure a plain vacuum would.

In any case, it'd be wise to flush everything in pg_operator and pg_proc
that has circle as an argument or result type.  (Does DROP TYPE do that
for you?  I bet not...)  There might be other system tables that have
references to circle, too.
