Wait for a bit before publishing a new version -- I'm going to push the
other patch so that you can merge on top.

Note that I'm going to commit a new function like this:

/** Raise an error to the effect that an object of the given name is already* present in the given namespace.*/
static void
report_namespace_conflict(Oid classId, const char *name, Oid nspOid)
{char   *msgfmt;
Assert(OidIsValid(nspOid));


For this patch you will need to create a separate function which does
the conflicting-name report for objects that are not in a namespace.
Mixing both in-schema and schemaless objects in the same report function
seems messy to me.
